I've started using Slack for this. I send messages to myself. And use the basic formatting to maintain lists, links and such. And various icons (green check mark etc.) to mark something as done, not relevant anymore (strike-through), and just delete things that are no longer useful to me. Of course there are limits on how far back you can go with the free account, but we use it at work as well. So far, it's been really easy - at least for to-do type of things.
