Lorawow - totally agree with the advice of aw1923 about, well, everything she said really.
- create "about blog" page so that your most recent posts are what visitors see
- do join Blogcatalog...at one point in time I was among the most active posters there. TONS of great people, and the staff are great folks as well. I just ran out of time in my days to keep up appearances there, but it's arguably the greatest site out there for bloggers to meet up and discuss virtually any topic imaginable. Plus, with a TON of highly knowledgable users/staff to interact with, you'll pick up many good tips on blogging in general (plus a very entertaining assortment of "off topic" style discussions). My only warning - it's highly addictive. Seriously...so addictive in can be like crack - but that's a good thing because it speaks volumes about the folks you'll meet.
- I remember being new and wondering how to quickly build up an audience. It's very tough. Just speak your mind and do everything you can to make visitors feel welcomed (replying to comments and engaging in conversation with them outside of the blog is great...met many new friends that way who share similar interests...some of them are amongst my closest friends now).
- never underestimate the power of the tags here at WP. If used effectively they can really bring a lot of traffic to your site. The key then is getting them to stay - and that's all about relevant content. Pay attention to which topics/search phrases people are finding you from, and then use that strategically to your advantage when you post (i.e., most search results seem to be about yard gnomes, then post away and make the definitive statements on the net about them). :-)
