I though mods were supposed to be rather hands off and mainly take care of the spam. Merging threads seems pointless, since the same topics are going to come up everyday.
By merging ongoing threads into a long and not totally related thread, mods accomplish the objective of cutting off ongoing conversations, confusing posters, and diluting the ideas they dont like into incoherent eclectic neverending and unfocused threads that nobody will read.
A dishonest way to handle the situation, in my opinion.
