Yeah, I can relate too, based on experiences from SOME forums. (INTJforum, for example, I feel pretty much ignored.) But I even felt that way here at one point, if some of you remember my rant from 18 months ago or something like that...
The "do you relate to this" questions are sometimes hard to answer -- there's only room for a 'yes' or 'no' but not clear what else should be contributed.
I mean, I guess my "answer" to it if one is being asked for is (1) post on various forums to find ones where your posts might resonate, (2) assume that people are reading your posts even if not responding, (3) the forum dynamics might mean people like your stuff but have nothing to say in response to it... I have a heckuvalotta 'thank you's' on one forum I frequent but probably only 20-25% of those max also receive a bona fide response, and (4) maybe what you're saying isn't as useful in a group setting and you can figure out a different way to say the same things that people could connect with more easily.
Just ideas.
