After slowly making it available to a few select people and working through their feedback, fixing bugs and iterating I finally did a "soft launch". i.e. Made it available on the landing page for people to use it if they found it. I also released it to the people on my short mailing list.
It is still quite ugly and premium accounts haven't been implemented yet, but at least it is being exposed to some more people. Hopefully that results in some more feedback as I add the last few features.
