Know any good task management or to-do list apps online?

I used http://www.rememberthemilk.com/ for a while. I liked it.

But in the end I wrote my own since it was pretty simple and I could make it exactly what I needed.

I’m a huge fan of Todoist.com. It’s very minimalist and the keyboard shortcuts are a breeze to learn.

Things (Mac + iPhone) http://culturedcode.com/things/ has received raving reviews.

Evernote.com

I use a mix of three: Evernote, Remember the Milk, and Google Calendar. RTM is perfect for school, because I put everything from all the syllabi in as a dated task, and get email reminders of homework, reading and exams.

@pygeek – I LOVE things. I have been using since beta. I don’t know if you can share on line though.

google calander and google docs are a great combo!

I second Todoist.com.

A friend recommended Basecamp by 37signals. I haven’t used it myself, but he’s a smart educator-type, so I thought it was worth passing along.
