When I started the SportsLocker blog in November, 2007 there wasn't a lot of opinion and information on the internet. If you wanted the latest news and opinion, then you needed to subscribe to the magazines, find a good hobby shop, or hope to find one of the few blogs dedicated to the hobby. There were very few to choose from.
Fast-forward a couple of years and the landscape has really changed. Today, you can read blogs that focus on specific types, certain teams, individual players and the "stats on the back." You can read Beckett's opinion and the anti-Beckett opinion.
If you're into social networking, there are several facebook groups and fan pages run by fellow collectors. Upper Deck and Steiner Sports also do a lot of work on facebook and offer fans special access, sales, and contests.
Personally, I think Twitter made the biggest splash to the collecting world in 2009. Bloggers, corporations, and card manufacturers did more than dip their toe in the pool - they dove in to the deep end. Not only do they tweet when they have a new blog post, but they tweet when they have an opinion. Following collectors and some of the companies on twitter can bring you alerts to sales from Blowout Cards to interesting topics at the Freedom Card Board. If you didn't like the latest box break from Beckett, you can send Tracy Hackler and Chris Olds a message on twitter with your opinion (within 140 characters).
We don't have a shortage of information today. We have more opinions and places to get the latest scoop than I ever could have imaged two years ago. The landscape has changed and continues to evolve. I'm really enjoying this new world of collecting: it's more transparent, has more opinions, and is fun to be a part of.
