After encountering a number of problems trying to filter Blogger feeds by tag (using services like Feedrinse and Yahoo Pipes), I’ve finally put together a solution that works: Shadow the feed with Feedburner. Enable the Convert Format Burner, and convert your feed to RSS 2.0. Use Yahoo Pipes to filter the feed (because Feedrinse seems to be broken). This let me create a feed that excluded all my posts containing the fbpost tag, thus allowing me to avoid yet another postgasm in Facebook when adding new import URL to notes.

I spent some time recently trying to figure out, using Google’s gdata API, how to retrieve a post from a Blogger blog if I know corresponding post id. As far as I can tell there is no obvious way of doing this, at least not using the gdata.blogger.client api, but after much nashing of teeth I came up with the following solution. Given client, a gdata.blogger.client instance, and blog, a gdata.
