I just signed up for Wink, which advertises itself as a people search engine. When you sign up you can add all of the social networking sites, media sharing sites, bookmarking services, mobile sites and other places that you use online (including your blog or website). I had some problems adding my myspace, it kept saying that the URL was not valid. But other then that, everything else worked pretty smoothly and they have a large number of places you can add, from the usual suspects like facebook, del.icio.us, digg, last fm and flickr to less popular inclusions like eyespot, jumpcut and stubleupon. It also features a widget that you can post on any website:

And a firefox plugin that can be added to your browser toolbar.

So far it seems pretty interesting. i would have liked some sort of inclusion of tags (like what correlate.us does). But overall, not bad. The problem is, I wonder if the social aspects of the site are robust enough for people to actually visit wink to view people's profiles and search. For me, it seems that the widget feature may actually be the most useful if included in my blog, myspace etc.
