I am in the process of updating my Guide to Media Monitoring I wrote back in January of this year. I am planning on including all the new blog search tools and custom RSS watchlists/feed services. There will also be some information about tags, specifically dealing with monitoring tags via Technorati/del.icio.us/Flickr, etc.
The guide is mostly geared towards communicators, but just about any user can learn something from it. Anything you think I should include? Perhaps some service that I might not have heard of? Leave a comment.
