While I avoid most social media, I do enjoy Twitter for a number of reasons. Not the modern form, but the 12 year old original invention: 144 character text messages sent to your phone.

Unfortunately I have accumulated a number of people I follow who are too interesting, and even after reading the initial message, I want to save the info for later to look into further. One of the worst of course is @donpark who seems to have a great deal of free time to look into curious and interesting technologies of all sorts. Cleaning out a previous phone that still had over a hundred saved notes brings up cool things like:
And that's just one person I follow over the span of about six months.
