I'm guessing the reply messed up and you meant to reply to me ?
I agree that SOTT is not great as an original source but their graph clearly states they got the information for it from the American Meteor Society, is that a more valid source do you think ?

No problem, I did find this link from the site which seems to validate the graph
Fireball Tracking System Analysis
While the AMS fireball log has many uses and benefits, based on the AMS reports alone it is not possible to make conclusions about an increase or decrease in fireball/bolide events from year to year. However, the data shows that reports submitted to the society have been increasing and a significant increase in large events was specifically noticed in 2012. This warrants further study. A pairing of DOD bolide data with AMS event data would prove useful to the scientific research of meteors striking Earth. In addition, the AMS reports identify the date, time, location and relative size of significant fireball events. This information could be useful in pinpointing events inside the DOD’s data sets. The AMS makes all report data available through our website and encourages the use of our data.

Well that analysis concludes talking about this very subject

Basically it's too early to say whether it's solely more people being able to report and verify or if there's an actual higher frequency in these events
I'd edge towards a combination of both if I was to hazard a guess as for me having a minor background in statistics you don't get such a high deviation from what was once linear progression without some kind of event causing the deviation, in this case I would hedge a bet towards more frequency combined with more people reporting.
I think the whole dash cam hypothesis is a straw man really also, as you don't need a dash cam in order to see something like this while you're driving. I'd also argue it's not more people watching the skies as evidenced by drivers, their focus is on the road not the sky (I hope otherwise they would be terrible drivers) and you don't need to be watching the sky to notice it light up
However I will admit this is merely opinion and until some conclusive evidence along with research is brought forward it will remain this way

Is it me or are these things becoming more frequent recently ?

I believe it's far more likely that it's a perception due to increased exposure to reporting of like events.
Notice that they're all being captured on dash cams? With the exception of cop cars, how prevalent were dash cams 10 years ago? What kind of mass appeal would these stories have without the videos, particularly outside of the country where the fall occurred? Consider also where most people were getting their news just 20 years ago.

Thanks mate. Will look at it later. Lets assume that there IS an increase. Lets discuss what the reasons could be? Could there be a debris field the earth is going through that wasn't around last decade when we didn't have twitter and dash cams etc to film them and instant tweet them?

We shouldn't be arguing about whether there is an increase. We should be debating the possible causes.

Once again, the increase in reports doesn't equate to the increase in actual number of events.
As for the past times, a sonic boom from a meteor could be confused with a sonic boom from a jet, thunder, or wrath of God (depending on how far back in time you decide to go).
We don't need twitter or dash cams to know when a large rock explodes over your country shaking homes, shattering windows, injuring people on the ground. If a rock exploded over any country years ago, I'm sure the news would have reported it and would have without dash cams and twitter.
