I read somewhere (really can't remember where) that 2008 was a year without a good quality content when it comes to web development and design. I disagree. There were a plenty of extraordinary articles, tutorials, freebies... you name it. In fact, there were so many of them that "best of" list would be too long. Instead of specific articles, I'll give you the best blogs that I enjoyed reading in 2008 and that I will definitively follow in in the future.
So, if you are interested in web design, web development in general or asp.net development - enjoy!
And, of course, JankoAtWarpSpeed :-) All the best in 2009!!
