I think some of you guys will find this free service pretty useful, it's very customizable. It allows you to make customized or already preconfigured "recipes" for certain actions. For example if you get tagged in a photo on FB/instagram that photo can automatically be uploaded to your dropbox/google drive/skydrive, etc.

That's just one example and there are many "channels" from facebook, twitter, tumblr, box.net, craigslist, gmail, gcal, evernote, foursquare, youtube, vimeo, skydrive, dropbox, stocks, etc. You can create relationships between these channels where if something happens on one of them it can cause an event/action to happen on the other channel automatically.

Other examples:

There are many more. There a 56 channels to choose from and you can make your own recipe, use shared recipes or use the pre-configured recipes.
