I have now added the "Addthis" button to my blog -- but because my blog is at wordpress.com, not a self-hosted service, I can't use the full service java-script button that would let people share a specific, individual blog post. The AddThis button (if hosted on wordpress.com) only lets people share the URL for the blog site as a whole. Does anyone know of a way I can add some equivalent of the "share this blog post" button for each blog post, but in a blog site hosted at wordpress.com? Or am I doomed until and unless I someday figure out a way to host my own blog! (Not likely to happen in the near future, though things like this make me tempted to consider trying to learn how, or whether it's possible/feasible for me, *sigh*)
Since I have a Mac, I'm not even looking at "get social."
