alt text for user icon heads

[denise]

Was thinking about the alt text for user icon heads and how we could change them to be better and more natural for screenreaders. I've opened bug 2037; the first comment says:

The userhead icon alt is [info - user] and the community is [info - community].
Change to [user profile] and [community profile] for more natural flow in
text-to-speech.

I'm trying to check that this is a change that would be useful. A friend of mine who uses a screenreader says that "user profile" and "community profile" would be the best mix of clarity and brevity and that the best thing to do is to make the first word the key word. But I wanted to post here to make sure that I haven't overlooked anything.

Thoughts?
