As a nondev, I just want to toss it out there that visiting other sites isn't an inconvenience. I mean, there's moments it would be convenient to everything in one spot, but its just moments. When its all more spread out, the freedom to discover things, try them, switch between them is what matters most. We do it now with lists, marketplace, blogging... and something so in depth as WoT as you've described is definitely be worth the time & effort to engage with separately. Especially as more options for types of feeds become available & as the social clients add the ability to switch between those feeds.
