Not really. If I want concrete information on something, like horror movie release dates, video game reviews or where to find rare horror movies or again information or film producers and directors and so forth, but a discussion based process such as a forum can’t provide anymore than a quick search can, or even rifling through Wiki links for more specific sources.
I do enjoy forums though, for sharing opinions and dwelling on subjects, so I suppose they provide that, but it isn’t anything technical, I suppose.
Also it’s pretty hard to find serious forums where the members don’t engage in a war of who can come up with the wittiest comment or how many posts you can rack up, so while I attend a few long time forums, I’m not much motivated to look for more, despite just how many Halloween and Texas Chainsaw Massacre oriented forums there are out there.
