I was once a type on-site gal. Until an envelope thrown across the room hit my keyboard just right, closed my browser on an absolutely monster post, and traumatized me for life. Then I moved to Google Docs. Until I had a shitty chromebook that would lag horrendously behind my typing (which I absolutely couldn't stand).

Now I use Google Keep! It's an absolute mess in there but it's safe (autosaves often), the text is nice, clean, and simple, and it's easy for me to jot down a quick thought on my phone and then elaborate or clean it up on my desktop later.

I have heaps upon heaps of notes. Most of them are just snippets of an idea, a line or two of dialogue I desperately want to jot down while it's raw in my mind, lyrics I like and may use in a post, reminders about things, vague concepts, etc. Once I start making some decent progress on any one reply though, I'll usually slap the thread title on it and "pin" it to the top of everything else. Then every couple of months or so I go through and do a (little) bit of clean-up.

I like it because all of my WIPs are right there, visible and super simple to pick up when the mood strikes to continue one.
