If you want to share medium-sized amounts of timely information, blogs and screencasts are the best conduits that I know of.

As for "expressing yourself" with Flickr, Facebook, and Twitter, photos, throwing pillows at people, and 140 character ephemera do not substitute for a solid, well-edited blog post.

"The time it takes to craft sharp, witty blog prose is better spent expressing yourself on Flickr, Facebook, or Twitter."

One word: SUBMARINE.
