Howard Rheingold has a series of videos describing how journalists (particularly) can use online tools to create their own radars (seek out information), filters (remove the crap), and dashboards (display the information). You can see lots of other video on his video blog.
I have thought recently about writing an online book (downloadable) or even a printable book about the “plumbing” that allows bloggers to integrate lots of sources into their blogs—because most bloggers are not really technologists and it’s hard to make some of these software tools work correctly. My thought was to connect the dots and come up with a Give your blog a shot of steroids “book” that would be really useful to non-tech-savvy bloggers. When am I going to do that?
