Anyhow, wishing you the best of luck with it. And again, I'm not an expert in any sense of the word. The above is just my honest reaction as I checked it out.
Hehe, it's fair and honest opinion so fair enough really :)
Regarding spammers, honestly you'd be surprised about the spread of customers that use TweetingMachine legitimately. This year though - I guess a sign of success - I've had quite a few problems with proper spammers on the system (and I have motivation to not support spammers - e.g. Twitter could turn off access otherwise), and have recently written quite a few automated systems to try and detect the buggers before they ruin it for everyone.
