we’ve been working on making personal sites and blogs interact more richly, similar to social networks and major publishing platforms. if you’re interested, definitely check out intro articles like these for details. for example, if you sign up for brid.gy (both wordpress.com and the social networks), facebook and twitter replies to your blog posts would show up here like normal comments!
welcome back! sounds like you’re thinking along the same lines as us indieweb folks. that’s great!
