Many threads regarding twitter are going on around there but the major one which broguht this idea into my mind was http://www.blackhatworld.com/blackhat-seo/social-networking-sites/96771-how-manage-thousands-twitter-accounds.html I know there are twitter automated adding programs out there, like Humming Bird and LivelyBrowser's app, but I didnt found any good PHP scripts for this. So here is the basic idea -> You can add unlimited accounts, follow, unfollow those who dont follow you, fully online so your bandwidth isn't used. This thread is for asking, IF something like this comes out, how much bucks worth it would be? Any features you want in this? Should I sell the SCRIPT or provide it as a service ( I prefer service so that script isnt resold)? Any more ideas? PS: Can anyone tell me all the 'limits' twitter imposes on an account? with API and without, Thanks!
