I totally agree OP.
There are so many threads on the same/ near identical/ similar stuff.
It's a shame as some threads are actually pretty in depth and genuinely insightful and interesting, and they can just get bumped to the cheap seats on pages 3 and 4 etc and then forgotten about.
Also- If you make a point on one thread on some new development, you then see many other similar ones, where unless you almost rinse and repeat the exact same post multiple times, your point also gets lost in the mire.
I can't say I'm a fan of appreciation threads but there's actually something to be taken from them.. Just a suggestion but people could make 'Official *insert HM here* threads' for each of them (both positive and negative) in the main forum and this should be the 'go to' thread for that person. The main gist of their 'journey' (puke) will all be in one place rather than scattered like the wind.
It would actually be interesting to see over time if people's opinions actually change all that much on them from start to end.
