I've been playing with subscription buttons to make it easier for visitors to subscribe to sustainablog's feed -- so far, I have My Yahoo!, Bloglines and My MSN. If you have other suggestions for aggregators and such, please let me know. Of course, I'd appreciate any links to information pages, graphics, etc., also...
Update: The My Yahoo! link doesn't seem to be working (though I took the code directly from them) -- any suggestions?
