I used post on a mobile phone forum called Lasyk, this was some time in 2004-2006...

The forum is long since dead and erased, but it was a huge forum with 100k members, subforums for just about any mobile phone made by mainstream manufacturers.

I remember managing to create a huge thread over on their misc forum, where I asked other users to post a screenshot of their desktop.

It just kept going, and I think it became a staple thread with 80-100 pages or so...
