We just recently launched the TapeOnline Blog with the hopes of keeping customers informed and providing them with another means of giving feedback. I'll be contributing frequently, so look for a little crossposting action every so often.
I've picked up Twitter. Even added a badge to my site. I really like the idea of basically having a continuous 'away message' type thing happening. It feels like it might end up being a lot to keep up with, however. We'll see how things go.
