Live Search OPML Generator
Andy Edmonds has posted about the all new Live Search OPML Generator...
"What does it do?: This app runs your query against the Live Search API with the feed: syntax, returning RSS feeds, and assembles an OPML file. You'll get the chance to choose from the results before generating the subscription list."
As an example, here's the search results on the query "ADO.NET". Some great feeds come back: The ADO.NET team blog feed, David Hayden's blog posts as a feed with category 'ADO.NET', Sahil Malik's feed that includes a number of ADO.NET posts, the ADO.NET Technology Preview MSDN Forum feed and plenty more.
What's great is that once you've decided which feeds you want to subscribe to, you select those and an OPML file is generated for you to wack into your feedreader. Alternatively, you could select all, then add the OPML file to your reader and then delete those that you don't want to keep. Or just add them as feeds to read within the Live.com reader.
Another nice thing Andy has pointed out is the potential to create Reading Lists from a search query.
