During my long, three-month absence, I took up Twitter and Facebook. While I think they are both huge time wasters, they provide a new dimension of communication at arm's length. Now with re-tweets I can share some of the creative sources I have found. Otherwise the only "Push" is to friends and relatives I don't get to see very much.
For instance, I connected with a classmate from design school who is on top of a lot of creative sources and organizations.
You are probably more up on Stumbleupon than I am but choosing graphic design as a topic led me to some useful sites. Some great Photoshop tutorials, an interesting typographic Flash® video and a photography site that reminded me of how much I don't know.
I met an author, yes, a real author with published novels and everything. He uses a little application called "Freedom" to keep him from wandering into the online wonderland while he is trying to write. Enforced discipline. All of this can eat up time and/or provide a series of counter themes when you are trying to come up with a creative solution.
In my stumbles, I found this list of classic web sites you should see.
