Well it would be interesting to see what the long term bubble is.. on my first week i got about 25-30. of course.. I was in a few other ones.. and everyone there was interested in my new forum product (I mod the HECK out of my boards and do not censor... so there is always something brewing, whether it is some new cool feature or someone going off about something that happened.) It would be interesting to hear exactly what you did to advertise your site.. other than sig advertisements / links additionally it would be interesting to see if the 40 users was a sustainable. In Week 2 do you have 80 users.. If that is the case.. I want to know what your doing..
