You don’t have to know everything to start something. You just have to know enough, and be willing to let the other pieces fall into place over time. In the act of doing you’ll learn how to do “it” better and you’ll learn more about what “it” is.
For example, it’s taken until now for me to figure out how to place all of those fancy Web 2.0 icons at the bottom of each blog post. But I figured it out (it’s a little more trouble than I expected). And now I’m glad they are there. They make it easier for you to spread the word.
So go ahead. If a post (today, tomorrow, next week) strikes you as interesting, click a button. People love to hear from other people about what’s interesting and what’s worth reading.
In the meantime, I’m going to try to figure out if I know enough to start Twittering (yes); and if I have time to follow people on Twitter (maybe); and if I have time to tweet (probably not).
I’d probably be better off doing a better job tackling my RSS feeds.
