Say if I'm using MassPlanner for my Twitter account, is it ok (or even just a bad idea) for me to constantly be retweeting the same posts over again? Just right now I have about 20 tweets advertising certain parts of my website, and just thought it would be a good idea to somehow cycle them so they're not burred. Also, just don't want my Twitter to look too outdated and have a bunch of old old tweets. Like.. maybe even if I just constantly deleted the old tweets and then retweeted them? What do you guys think?
