Thanks CocoLion, it's so nice to hear that everything worked well.
SEO is such a tricky question. Once we have launched the blogging feature broadly this is something that I will return to. What I envisage is that bloggers will get to choose whether they want their blogs to be available to search engines (Google). I will optimize their blogs for SEO as far as I can, so this is something that individuals don't have to worry about.
What we will also do is allow people to tweak some settings that might make it easier for Google to find their site when people search for related things.
The title is an important part of SEO. The likelihood of Google putting your site in a search result is definitely higher if your title contains words from the term that a person is searching for. So a title like "Fashion After 50" would be effective if you expect people to search using the words "fashion", "after" and "50" in the search term. It would be even more effective if your site address contains these words, for example, "fashionafter50.lookfab.com".
That said, I wouldn't make this a top priority in coming up with a title. One can never predict what people are going to search for, and I think it is more important that the title reflect what the blog is about, the personality of it, etc.
Also, it can take a very long time for SEO to start kicking in, and in the beginning you are much more likely to get traffic from the forum, and from other bloggers that link directly to your blog (in their posts, or also in their blogroll). We will also help to make lookfab.com blogs discoverable by featuring them on youlookfab.com from time to time (only blogs that want to be featured, of course).
