Blidget - make a widget of your blog, you get stats and promote it in a gallery, for similar offerings, see here.
Great idea, this is what the new blog directory is, not just a link to a blog, but now you can take the blog with you…Technorati has a blog directory module, maybe they should include widgets for every blog.
me.dium - visually see and chat with contacts and other users online, based on the sites you visit. Chatsum (also see Gabbly, Itzle, etc…) lets you chat with people looking at the same site as you, but me.dium takes this further by harvesting the sites you visit, and then placing you in a social context…seems to be based on the social behaviour of other chat recommendation sites like OthersOnline.
Change.org - a social network, and blog network similar to citizen journalism sites like Newsvine, but dedicated to the topic of social activism…I really like the idea of topic based News 2.0 sites.
Change.org isn’t neccessarily tied to news, where blog networks like Sponit, Gather (also has groups like Changes.org) and Loopnote are for general information, Change.org is topic based…I like the idea of mini-blogospheres.
