This is not as much a tutorial as it is a complaint of overkill. I was recently searching for a way to automatically retweet tweets by those who follow me. Currently, I can read a tweet and then manually choose what to retweet or whatnot. In my search, I came across an article that boasted a solution as "News: How to Auto Retweet Using Yahoo Pipes".
Well, it does what it says, more or less. It doesn't perform an actual retweet, but rather it simply resubmits something already tweeted as a new tweet. Granted, if one want to grab an RSS feed from one of their followers and repost their tweets to their own Twitter page, then that can be accomplished by what I am about to tell you or you can simply cut to the chase and not use Yahoo pipes at all!
Here is the scoop. In the article located at http://www.gravityswitch.com/blog/how-to-auto-retweet-using-yahoo-pipes_97/
, it has as one of the steps to use twitterfeed.com. Guess what? Twitterfeed already HAS a publish feed option. That *is* what is does - reposts to various social networks, including Facebook and Twitter from feeds!
So, I do not know if the guy that wrote the article was testing a proof of concept or what, but just so that everyone knows, you do not need to use Yahoo pipes to accomplish the task of getting a feed (any RSS feed) to repost to Twitter.
