Starting a blog

[hyphenate]

So what tips do other bloggers have for me and others eager to start one? Mix politics with other stuff or maintain more than one? How much personal info (nothing traceable, though!) do you reveal? I'm not so worried about "life" stuff--I've been online for 17 years and I've never worried about that (although it is getting more difficult to maintain that sentiment) kind of stuff.

How often do you "blog?" Once a day, like a diary, or whenever the mood strikes, even if it's ten times on one day and nothing for the next week? Is it mostly personal opinion, or are most bloggers involved in spreading news broadcasts as well as stating their opinion?

Would like to know what route others are following.
