How old is this forum? I attend a few different forums, and some took a while to get rolling. As this forum is mostly specific to Ernie Ball products, its scope is limited to people that use them. That's not bad, but it may limit the activity level. As their products don't require a lot of technical feedback, like debugging computer hardware/software, there isn't the same need for feedback for EB products.
I agree with you, that this place could be hoppin' with users, discussing gear and music, however. Maybe having more input in the General Music Discussion pages will trigger that. Tell your 'net friends about the site, post related links and draw in people from other sites. This site may not have a huge attendance, but at least the quality is there. Too many forums are just flame war venues, and that gets old very fast.
Keep on postin'
