Just make sure not to merge every single thread after the matches - what I love about this place is that we've always got new threads when something new has happened, or something different.
A lot of forums don't want their users to create new threads and even got 1 single thread for each player and it takes away the dynamics of the forum. Just look at RAWK, they got 130 pages threads for each player - so say Babel did something in a particular game and some user wants to highlight it, then he has to post it in that big 130 pages thread and it loses it's meaning after a few posts.
Last night someone asked why Anderson didn't play, but the thread got merged with something completely random (I know the whole merging last night was probably some kind of demonstration from the said mod) and it'd be a shame if you started merging all post-match related threads.
I understand why general post-match moaning should be merged, but don't turn into to RAWK so that we only got 1 thread after the match, it'd ruin the debate in my opinion. Say someone want to highlight our tactical mistakes then that thread shouldn't be merged with a thread where someone talks about our strong defence. Just merge threads that are identical, if you merge everything then we'll have one big thread discussing 10 different aspects of the game, and those discussions would cross each other multiply times and people wouldn't know what's up and what's down - then it's much better to have those 10 different aspects of the game discussed in 10 different threads. Of course some of those aspects could be very close and would need merging like yesterday where we had a thread comparing us to Reading and a couple others focusing on our defensive take on the game.
But then there was also a thread asking how we were any different from Chelsea and Liverpool - if you merge that with the Reading comparison then the original question would soon lose meaning and cross with Reading comparisons - that might be what you want, but I'd prefer two separate threads in such case.
Then again, that's just how I see it.
