Something the would be very useful would be if, after a SHB run, there was an extra column in the CSV file for RSS. Where sites provide it, a RSS feed for the users posts on that site would be good since it could be fed to RSS aggregators to make sure the links/posts/bookmarks are found.
I want to second this suggestion.
Pinging my rss feed each time I do a post really gets the attention of the search engines very effectively. I came on to also ask about the possibility of getting a report back of the url address of the backlink address when Bookmarklovers posts for the purpose of backlinking and pinging my backlinks. This is generally a very effective strategy for me and I have not been able to do this with BML.
