Overall, I like the feature. Some people use it in annoying ways (No,
I will not be more likely to subscribe to you if you fill the video
player with "SUBSCRIBE TO ME!" links), but it's a neat feature and
opens up some interesting possibilities.

I've found the user interface to create the annotations a little
tricky, though. In particular, the editing preview often continues to
show the annotation even after it has, actually, disappeared according
to the timeline, which makes it a little hard when you're trying to
time them exactly.

It seems a bit odd that you can specify the exact frame the annotation
appears and disappears, but the video player only shows minutes and
seconds. Actually, it's possible to be fairly accurate specifying the
start of an annotation, but not the end. Perhaps a "end annotation
here" button to place the end of the currently selected annotation at
the current position on the video timeline. (Am I making sense? I'm a
bit tired and I can't tell.)

A nice idea might be "centre vertically" and "centre horizontally"
buttons. Take some of the guesswork out of positioning subtitles.

On the whole, a nice feature.
