In my experience, trolls will gladly climb the paywall to be able to troll.
So a paywall will not help a lot, methinks.

I hope it's the waffles!

I run a web-based online football manager game, and for July, I see:
40.19% Firefox 3
30.05% Internet Explorer 7.0
8.01% Internet Explorer 6.0
6.37% Opera 9
5.95% Chrome
4.49% Internet Explorer 8.0
1.95% Safari
1.65% Firefox 2
98,66% of my traffic consisted of these browsers
42,55 of the traffic was coming from IE
----------
In june, the numbers read:
40.75% Firefox 3
30.06% Internet Explorer 7.0
8.20% Internet Explorer 6.0
6.09% Chrome
6.04% Opera 9
3.39% Internet Explorer 8.0
1.99% Firefox 2
1.86% Safari
98,38% of my traffic consisted of these browsers
41,65 of the traffic was coming from IE
----------
Way back in January, the numbers looked like this:
36.51% Internet Explorer 7.0
35.49% Firefox 3
13.70% Internet Explorer 6.0
4.95% Opera 9
3.92% Firefox 2
1.95% Chrome
1.54% Safari
0.58% Firefox 1
0.40% Internet Explorer 8.0
99,04% of my traffic consisted of these browsers
50,61 of the traffic was coming from IE
----------
Whether anyone feels like making any conclusions based on these numbers, I don't know :)
But from my end, it seems I had the biggest changes in IE/Non-IE ratio in the months November last yer until April this year...

I run a website with a bit of traffic, an online footiemanager, and always keep an eye on browsers, their usage and their performance. Here is a little blog with some interesting results when it comes to JavaScript and performance. http://www.managerleague.com/blogperma.pl?id=1858
