Blogging Questions

Today I set up my blog and hope to learn som new skills. My thoughts and Learning about Web 2.0 started with a previous blog I created while doing my BALIM, at Charles Sturt University. One of the hard things about this for me is the nagging question, do I have anything interesting to say? I discussed my plans for this attempt at Blogging with my colleague, who has created and regularly uses blogs, and he pointed out that Wordpress has a good easy interface and I noticed that Tim had posted a comment on the NSW Public Libraries Learning 2.0 course blog recommending Wordpress over Blogger also. However, I am sticking with Blogger for now because I know it's basic features. What have I learned so for that I didn't previously know, How to delete a blog. Thanks
