The site TechnoBuffalo.com launched today, and already has some high quality content on it.
On the educational side, I've found their tutorials about putting together your own little space on TechnoBuffalo to be very informative. They cover topics such as appearing confident on camera (for video reviews and such) and how to actually get goodies to review. This is useful whether you plan to carve out your niche on the web at TechnoBuffalo, or if you have a blog already.
On the fun side, I enjoyed their Five Awesome Sites for Tech Enthusiasts. Specifically, I found the You Suck At Photoshop tutorials to be hilarious. They aren't exactly family friendly, but are a blast to watch.
