If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
My Firefox often slows down horribly when opening Facebook, and I don't see myself procrastinating less. It makes me angry when it happens, but I stay and wait until the page is loaded. (Or go drink some water while it is loading, etc.)
Could it perhaps be a difference between random slowing down and predictable slowing down?
Do you have an accurate view of how much you are using facebook? Do you have hard data, and know how it changes?
