I like watching GitHub repos because one day I might need to use a library that I've added to my watched repos list. It's very easy once you authorize GitHub access to your Evernote account. You just enter your GitHub user name and choose an Evernote notebook. The ReadMe of every "watched" project will be added as a note to your chosen notebook. GitHub repos are refreshed every 24 hours to check for ReadMe changes. Once the ReadMe changes, your Evernote folder will update too.
If you plan to use Evernote in this fashion, I recommend mapping your GitHub updates to a specific folder or setting up a separate free Evernote notebook if you're concerned about security settings.
