A frequent strategy I use this days is to leverage several social web sources to search for specific subjects.
I then use RSS and Google Reader to consolidate the results into a single view
For example, this week I am working with Microsofts “Hyper-V” virtualisation technology.
I start with Google Blog Search
which produces a search-results RSS feed:
http://blogsearch.google.com/blogsearch_feeds?hl=en&q=hyper-v&ie=utf-8&num=10&output=rss
Then I go with Twitter:
http://search.twitter.com/search.atom?q=Hyper-V
And Friendfeed:
http://friendfeed.com/search?q=hyper-v&who=everyone&format=atom
Another good one to add would be social bookmark sites such as http://delicio.us
So in Google Reader, I created a folder called “Hyper-V” and added all three feeds:
The result is a very neat consolidated list of posts, dynamically updating all the time, based on the search term.
