Google Blog Search is an invaluable tool for searching news and views off the beaten track. It scans the blog posts of the great and the good, spanning major companies to everyday journal writers.

Today Google have announced some key changes to the service. The alterations should make searching easier, more intuitive and user-friendly. The most notable key addition is the introduction of an RSS feed. This will provide quick updates straight to your feed reader on any number of desired topics.

As with other trending sites, including Twitter and Blogpulse, Google Blog Search now also includes Hot Queries. This will give you a rundown of the most popularly searched for terms, whilst Latest Posts notes the most popular stories being discussed.

No doubt further integration with the likes of Reader and iGoogle will come about, but Blog Search should now be a far more accessible tool. If you haven’t used it before, it’s well worth a look.
