0. I would have linked to the product, but I'm honestly trying to avoid anymore sources of traffic. It's a microblogging platform wherein all posts have a shelf life determined by the user. Currently building the iOS app, but won't release that until the product can handle even more growth.

1. I started part time about a year ago, full time about 6 months ago. I recently completed the survey (I think created by Sean Ellis; with a few tweaks), and implemented based on that. This resulted in a spike in growth in the past week, but I fear that'll only hurt if the product stays as slow as it is now on the current hosting situation.

2. Server space is the only cost limiting growth, unless the stats have fooled me and it's really not at PM fit; in which case marketing would be another cost.
