My two years old blog post made the front page on reddit: http://adblockplus.org/blog/anatomy-of-ads
Right now it is number 7 on reddit and apparently stayed somewhere around that position for the last 14 hours. The blog post had 24 comments in 10 hours (when I checked my mail this morning I thought I am being spammed) and the current visitor rate is several times the usual number. Consequently, the load levels are around 0.20 which is a relatively high level but there is still plenty of room and the response time doesn't seem to be higher than usually (according to the monitoring service the response is occasionally delayed by up to 100ms compared to the usual numbers, this seems to come entirely from the database which needs to process more requests than usually). So big thanks to reddit for allowing me to check the resource reserves of my server, apparently those are plenty
Oh, I don't say it doesn't help - the attention coming from fligtar's blog post is certainly worth a lot more than reddit users who will be gone the minute the link disappears from the front page. But fligtar won't help me stress-test the server.

Yes, that's pretty common. c't 4/2009 for example has some "essential" applications on a DVD - including Firefox and five add-ons (GreaseMonkey, Flashblock, Adblock Plus, Firebug, DOM Inspector).
