I want a nice way of keeping track of who I haven’t talked to for a while, so I don’t fall out of touch with people. Should be pretty easy, with all our contact information online.
Somewhat surprisingly, I wasn’t able to find anything I liked. The closest I came was https://gist.com/, which is a cool tool to see all your contacts from all your social networks in one place. But it didn’t have the one feature I really want — the ability to sort by the last time I contacted a person divided by the rough frequency at which I’d like to stay in touch with them.
So, I hacked together this: http://www.joshhaas.com/contact/. It’s primitive, but it also does exactly what I’m looking for. If anyone knows of a professionally-maintained tool that can do what my thing does, please let me know!
