So far, I've got:

1. A book to-read list on my kindle (I download samples for later reading)

2. A blog post to-read list in Feedly

3. An online article to-read list in Pocket

4. A real-life things to-do app on my phone

5. A "maker" things to list in Asana

6. A tweets to-read list Twitter bookmarks

There's got to be a better way, surely?
