Saab:
I don't like the ads in the side bar - certainly not on thread pages. Nor do I like the google ads under usernames. But I simply block them all, now. I do not see a single ad, anywhere on the site.
Is that counter-productive by IB? Very possibly. But as far as I am aware, the ads are here to stay.
I'll agree with the others who say it looks awful. But I'll add that I don't currently use an adblocker because I find that very few of the sites I visit look so bad or overloaded as this one does now.
If an adblocker can be configured to work only on certain sites i.e. this one, then I'm going to install and use it. Even if that means missing out on those useful or interesting ads that I previously clicked on when visiting this site. Ho hum
