Twitter to Twitter
On a business level we want to tweet 300 twitter accounts, with tweets at 5 of our business twitter accounts. so 5 to 300 as twitter to twitter. I do not have an rss feed for those 5 sites, everything is posted to twitter, we just want to select which other sites out of 300 should also post this news automatically.
Good idea but it's a bad idea without first verifying all of the accounts involved in this "sharing" to help prevent content scraping of other twitterers.
