I agree, although I'd add that if it comes down to either a 1 liner and a link vs not posting at all, just post the 1 liner. Something is better than nothing. If you can however, obviously give a good summary.

Except that it is not really fair to ask someone who has already put a ton of time and effort into a long, informative post, to spend even more time because you are too lazy to skim the article.

I tend to agree with Adam on the length of a post.  Generally, if the post runs to any significant length, then it should probably be posted to the wiki in an appropriate place.  The forum is a place of discussion, not dissertation.  The wiki is very easy to change.  Long articles can be easily broken up into smaller ones, short ones fleshed out with detail etc.  Also, I wouldn't be too concerned with a half-baked idea.  If you have enough material to write a post too long to be easily read, then it's at least on the way to being fully baked - so post it to the wiki.

Process them.  You want it done, you do it.

Welll, really,  in some cases there may be some things that need to be done, are holding up further work, and can only be done by a few people.  In those cases, if nobody gets on their back it will never get done and we would have a problem.

But for most other stuff, it makes no more sense to say that people who present ideas shoudl implement those ideas than it does to make a rule for yourself that you will always do everything you think of.  We need to pool our brains as well as our hands.  Many hands make light work but with enough eyeballs all problems are shallow.  Much stuff that gets suggested or thought about won't be worth doing in the end but suggesting and talking and even pushing for it is still good.  We can use collective, additive thinking (rather than subtractive groupthink which produces behaviour dumber than any one person) That someone has a good idea does not mean that they personally are in a position to do it, obviously.  Fact, like it or not. Their opinion might be worth *less*, but still something, and not necessarily.

A culture in which people make the ultimate decision where to spend their own time, instead of where other people decide how other people will spend their time means less unnecessary work.  When you are faced with a couple hours of work you tend to think a little harder about the harsh realities of whether it is really worthwhile.
