Happy New Orbit cycle Earthlets. I had a zarjaz time reading 2000AD comics over the holiday. This post is nothing to do with that but is a collection of random resources that language teachers might find useful (and myself, for reference).
Pocket is a marvellous app for saving stuff to like Diigo, with offline reading and text-to-speech functionality so you can recommend it to your students and it can help them with checking pronunciation of a text. It works on Android, iOS and in the browser on a computer.
Stack Exchange is useful for anybody doing stuff with analysis of language and spreadsheets or computing, etc. It started as a computing Q&A forum but now there are communities about a lot of different stuff. It can also be a good resource for ESP teachers. You never know, you might even get inspired to write a webapp or set up a website!
