IFTTT (If This Than That) is a service to monitor a source and conditionally post to a destination.
I’ve setup WordPress blog posts to Twitter and Facebook status update.
It seems simple enough to setup and it takes a lot of work off of my hands. Also, it allows me now to use my blog even more than before to post pictures and comments and everything. The advantage is that, once I (have to) leave a service such as Facebook or Twitter all my content over the years are still available on my own server. This to me is what the internet was about in the very beginning when I started my first homepage more than 12 years ago.
