I do have some, the most interesting ones running in Huginn https://github.com/huginn/huginn

I use it for some data gathering and most importantly, notifications and a 'personal newsletter'.

There are quite a few people in this thread that wrote things that send notifications to them; my setup kinda goes the other direction, because I don't want to be constantly spammed and nagged by my own bots.

So for instance, there are some software projects I want to keep up with, but I neither want to be interrupted by notifications, nor do I want to have a bunch of spam in my RSS reader. So I set Huginn up to watch some RSSs, some webs and instagrams and things like that, collects them, and then sends me one summary mail every two days.

Similarly, I also get one Pushbullet notification with all the headlines from a news portal every day.

Huginn is great, you guys.
