File this one under the "new to me" category. I've dug up a fun little link report that MyBlogLog does. I can use it to see which blogs are sending traffic to other blogs. For example, SEOMoz seems to have had 7 visits from MyBlogLog enabled sites, SearchEngineLand has had 11 (most thanks to the funky SearchEngineJournal) and SearchEngineWatch has had 5. I assume the figures are for today - actually, I've not seem them change yet and they are low. They could be a snapshot report rather than a maintained and updated one. In fact, the style and branding of the page looks old-school. I suspect this is an old feature rather than a new feature.
Did you know you can access MyBlogLog via a Yahoo domain now? http://mybloglog.yahoo.com/
