I can't really fully answer the question... not in 4 choices.
This is the age of social media... forums like this, are not as 'hip' ( or whatever the young folk say these days ), as the newer forms of media. And, well honestly , the new forums of social media are not really quite as good for displaying the kinds of information that had been a part of the pellet forum now, or in the past. Search functions are darn near non existent on places like Facebook, and all that. Yeah, well technically they do have search functions, but I've never really found them all that great. It's very hard to find any information that's more than a few months old.
Ah, anyway... Seems with the more modern forms of internet media that are being used more frequently then these older style forums, the attention span is also growing shorter. People ask the same question repeatedly, often people grow weary of responding in a thought out manner, because in the long run their comments fade way into swamp of older questions and such. Yet, if you want the attention of most younger folk today, product marketers have to play that new media game... In some ways, the newer game is better for marketers , they can get their latest message out fast, and well, frankly if the old message didn't work, it fades into the distant past and largely becomes forgotten.
I do prefer forums like this from a technical point of view... but I fear this type of site , is getting closer to the ways of full service gas stations.
