Cynthia, I agree with others that usually blog contains much more text and it's good for SEO. But I saw also a lot of TGP type blogs like this one:
http://females.erolog.nl/ that listed in
Bloggernity.
I'd list your blog in my LL, because I know that TGP type blog has many advantages in SEO comparing to a freesite or TGP if it uses blog promotion methods: RSS feed promotion, pinging XML RPC servers, linking with other blogs and blog directories. In other words, blog for me is rather not a content, but a technical part. Though I'm think that some blog directories like
Blogarama will not list it, because they are have more strict requirements to blog's content.
