Dave Winer announces TechJunk, a curated stream of breaking stories about new products and new features of existing products. If you’ve been following what Dave’s been doing with NewsJunk, the site will be familiar. The emphasis is on breaking stories — as highlighted on the counts page where stories live for no more than 24 hours. I’ve found the NewsJunk site to be highly informative, and expect the same will be true of TechJunk.
