Is four sighted fireballs in the last 24 hours really considered a lot?

Not really. I've been fortunate enough to observe 100's (probably not far off the 1000 mark) in the space of 8 hours back in 1998.
If that happened again now, I'd bet quite a few people on this forum would be forecasting the end of the world as we know it.

That incident in your link was predicted as a regular meteor shower, and anyway there were only a few actual "fireballs" as it says in the link, no one reported "hundreds" of "fireballs", most were shooting stars, streaks in the sky.
Valentin Grigore of the Romanian Society for Meteors and Astronomy is an experienced meteor observer who monitored the Leonid shower from Targoviste, Romania on the night of 16/17 November. In a 6-hour observing period under dark skies he saw 796 meteors, of which 193 were fireballs. When the shower peaked in Romania, with 200+ meteors per hour, nearly 40% of the shooting stars were brighter than magnitude -3. Many were brighter than Jupiter, Venus, and the full moon.
Leonids '98: Fireballs Galore!
(First Reports from Observers)
By the Editors of
Sky & Telescope Magazine
THE LEONID METEOR SHOWER has come and gone! The deluge of reports that poured into Sky & Telescope's office over the last few days has now dwindled to a trickle. If not for these reports, S&T's editors wouldn't have much to say about how the shower went, because -- sob! -- we were 100% clouded out.
More fortunate observers all over the world tell the same story: this year's Leonids were rife with dazzling fireballs, many so bright that they cast shadows. Long-lasting trains were common. Many skygazers counted meteors at rates exceeding one a minute, though the hoped-for "meteor storm" with rates of many meteors per second never materialized -- despite some reports to the contrary (see the end of this article for an explanation).
Here are excerpts from some of the Leonid e-mail we've received, in chronological order as the zone of the shower's visibility swept westward around the world over the past two nights:

Just got back in from a brief look at the sky... and the show is still going on...! Even though it's rather cloudy -- not thick cloud, low, misty stuff leaving tantalising gaps -- the meteors are visible through the cloud, travelling very quickly, many of them ending with terminal flares and bursts. I just saw three magnitude -7 fireballs in the space of 5 mins, and one amazing -9 or so fireball which ended in a flare which lit up everything... Even in the areas completely hidden by cloud there are flashes and burst of light, making the sky look like there's a WW2 artillery bombardment going on, unbelievable, truly spectacular.... The meteors are travelling far, far quicker than I expected; if you think you're going to be able to follow them in binoculars, you're wrong, they're faaaaaaaaaaaast!!!

For telescopic [meteor] observers like myself [who monitor a shower's very faintest meteors with optical aid] tonight was a major disappointment. Where were the faint meteors? The incessant flashes of fireballs -- some coming just seconds apart -- were a great distraction too. At times I lost my night vision thanks to the -12 or brighter events peppering the sky. Then there were the demands to turn the 'scope on to the long duration trains (some as long as 20 minutes). To be fair, it was an awe-inspiring sight to see crepe paper, hollow spiral trails, and new nebulae in the sky.

Oh, what a night. The sky was clouded over 95%. Through the holes in the clouds we observed for half an hour [3:45-04:15 UT Nov. 17). And we saw the most beautiful meteors we have ever seen. Sometimes the clouds were beautifully lit up by the fireballs behind them. To give a magnitude to the meteors is difficult because of the bad weather conditions, but I say most were -4 and brighter.

I don't have words to say what happened the last night. About 15 of us on the summits of Gran Canaria, at 0:00 UT Nov. 17, were preparing our cameras and finishing our preparations when the [shower's radiant rose and meteor rates began] ascending in moments, fireballs crossed the whole sky.... Some reached magnitudes of -9, most left a train of several seconds and the most brilliant with trains 5 minutes visually. As the radiant rose higher in the east we observed bigger activity, for moments we were not able to record our count because even in intervals of 2 seconds we saw up to 6 meteors. Until dawn the activity maintained, with some ups and downs, but always characterized by fireballs.... From 0:30 to 6:00 UT [one observer] counted about 800 meteors.

I observed the Leonids for a brief hour Tuesday morning (between 3:15 and 4:15 a.m. EST) and, despite at least 50% obscuration from clouds & fog, witnessed 2 meteors per minute right up until the sky completely clouded over! Several fireballs displayed bright green and violet.... Never before have I seen a meteor shower that made me scream and squeal with such delight!

I was seeing meteor rates of near 100 per hour off and on this morning. I was seeing better than 300 PER HOUR THROUGH DENSE FOG after 5AM CST. This was only the fireballs and doesn't even count the fainter ones....

Just came in to warm up. My feet are frozen. So far have observed for 3 hours Teff under nice clear skies -- limiting magnitude 6.0. SIMPLY UNBELIEVABLE!!! At times rates as high as 5-6/min. Fantastic fireballs illuminating the horizons. Geese on the lake going nuts. I've never seen anything like this before in my life!!!

I headed for the countryside at 3 a.m. Central Time and watched the skies for one hour. We counted over 100 meteors including more than 50 fireballs. The fireballs left streaks of green, yellow, pink, and red. Two lit the sky so one could see the surrounding countryside.
The meteors were streaking from every direction.... We witnessed one spectacular pink fireball on the southern horizon that lit up the sky as if lightning had flashed.
I have watched a number of meteor showers but nothing compares. I will never forget the Leonids of 1998!

Many of the daytime fireballs we are seeing now, including this incident of four and the Russian meteor do not coincide with any known regular meteor showers.

I am pretty sure it would be hard to miss such an event, compared to these pea shooters. Till then party hardy like its 1998.
