The immense popularity of Twitter has created all sorts of demand for more services. Currently much of the tasks are rather manual such as following, direct messaging etc.
But thanks to sweet souls out there, it’s now possible to automate some of these tasks using services which are mainly available for free.
If you prefer to auto-follow all your followers, Tweet Later can do just that for you. On top of that there are many other goodies such as auto-reply, email digest and so on.
Auto-reply setup involves creating a filter to auto-forward Twitter emails to TweetLater. It’s preferable that you choose your Gmail account for this stuff. If you did, make sure your Twitter’s email is setup under this account too. There’s a step-by-step tutorial provided in case you need one.
Another service that is quite similar to Tweet Later is SocialToo.
So go check out and pick the one you prefer or both.
