The small list above is of some blog sites I've found and used information contained within their posts to assist with some support situations and represents efforts by their authors, who actually implement technology and post some of their reviews and opinions. They've decided to share some of their experiences in support and information such as this that's not written for promoting a particular manufacturer's or distributors products but instead written to try and inform other users and implementers of technologies is invaluable information.
It's a rare treat to find computer support blogs that have their content provided by actual technical people and not a paid writer. Non-commercialized unbiased opinions have their advantages. Their authors don't just talk about technology, they implement it as well.
