Age has nothing to do with it...I have a WP blog which I launched in January and within two months I was fully indexed. I'm now pulling in traffic from all three major engines (after five months) and hit 13000 pageviews last month. There are tons of opportunities for blogs to pickup backlinks from major authority sites like Technorati. You just have to work it.
Yup! Thanks for the compliments. I'm having a blast with that site, and still tweaking it here and there. ps: Hi Sarah!
