sweet.. 10 is a good number. Its also a number you can use to turn this into a business.

If you ever ditch the freemium model, say first 3 sites are free and the rest you charge for.

This will please the common joe schmoes like myself who have a couple of sites but might not want to pay (my uptime isn't super critical...yet). Secondly it'll show other business who have 5+ servers (like we do at work) that you're taking it seriously. And more importantly it'll bring in money for you to cover the costs and maybe turn it a real business.

Pingdom has other features that they charge for so it might be worthwhile looking there...if you ever want to run it as a business. I know on your site it says this was a past time project and maybe you'd prefer to keep it just that...which is totally cool

First of all I don't think this will become a Pingdom clone/killer. Ease of use, simple, and unobtrusive are values that I will continue to value when deciding on where to take the project.

If I do decide to take money for premium features (more monitorings, higher monitoring frequency, history/statistics) I think I will do so with the hope of getting enough subscriptions to cover the server costs. If it provides more revenue than that I could see myself providing SMS notices to non-paying and paying users alike.
