It's not perfect, but I use https://simplenote.com/

Someday I will build my own clone of Simplenote/Notational Velocity/Taskpaper/Drafts/Bkmks.com...

1. From mobile browser, share to Simplenote adds a new note with title + url.

2. Not often.

3. Not often.

4. Also Simplenote. Also used Notational Velocity: one note per JIRA ticket.

5. I wish Simplenote's tagging system were better (more like TaskPaper)

- I wish it were simple to add (markdown) images like Github. (CTRL-V automatically uploads and inserts markdown).

- Also Simplenote added some features that get in the way (I just want to type `[`, but Simple note opens this inter-note linking interface)

- Notational Velocity supported rich text, but I just wanted everything in plaintext, especially when pasting information into a note.
