Most of the thread were made during seasons 1-3, I remember there were new threads every day then pretty much because there were so many supporters for them on here
A lot of that died by season 4 though, people were disappointed that the show cut their scenes back to almost nothing after season 3 had that whole arc of them working together against Lionel and getting a bit closer, then suddenly in season 4 they had no time for one another at all. I think that Chloe finding out Clark's secret made a difference there maybe, because she became very protective of what Lex might be up too with Clark after that
