One issue for me in terms of posting stuff about projects is that sometimes an open forum is just not the place if info is confidential, or needs to be restricted in some way for whatever reason. I wouldn't want to work on a project for months only to find that it had been 'raided' before it was complete or made safe, simply by inadvertent posting. Sometimes the locations just can't be disclosed. Sometimes I'm working on club projects, and so plenty goes on the club forum (and occasionally the open club website), but it's either not relevant to a wider audience, or it's necessarily confidential again. Sometimes there's an article or other publication being produced, which again means a certain amount of restriction because of publication dates, etc. I'll always try and join in on 'general' discussion if I can contribute anything, but sometimes I find it's best to sit on your hands if you don't know the full picture or can't divulge the big picture - or just don't have a clue what anyone's on about!
These aren't excuses, but valid reasons why members (me at least) may read but not post as often as we'd like. It's not like I'm short of topics to discuss. And I'm on UKC daily, as I consider it a very useful resource and a great place to keep in touch with like-minded people. I find the regular bickering genuinely hilarious, and would probably miss it if it were gone, but I'm funny like that - I can be entertained by someone else's argument for ever. Thanks to Pegasus and Badlad and the team for all their hard work and commitment - it is appreciated, believe me.
