When displaying your Wordpress blog RSS feed (e.g. http://alecthegeek.wordpress.com/feed/, as given by the RSS button on the right of this page) in another tool or website, it may be that each entry has the name of your blog where you would expect to see the post title. In that case change the feed URL to http://alecthegeek.wordpress.com/?feed=rss (...?feed=atom also works).
Tested using Jaiku, but I'm guessing this applies in other tools that consume feeds.
Update 27/Aug/08 -- also works with other Wordpress installations (besides than Wordpress.com) and is needed by Friendfeed
