Embed gists/code snippets from https://git.io too!
Created by: dragon788
#524 (closed) and #57 (closed) were awesome features. Perhaps related to this would be the ability to pull in gists/issues/code files that are linked via https://git.io. This service supplied by GitHub is restricted to Github links only already, so it shouldn't be much different from the code to embed gists/links already.
If there are any feasibility issues let's converse, but I was really hoping to create some memorable short URLs to gists/wiki pages answering extremely common questions in the channels I frequent (with the goal to potentially eventually use a bot to supply these answers on demand).
