Consistency in naming

In creating user documentation and site copy, we want to ensure that we have consistent naming, rather than calling things one thing in one place, and something else in another. Here are things that could potentially have multiple names, where we need to pick just one and stick to it.

Please add to this page with any other things you can think of where we need to stick to just one name.

Userpics/icons
I'm not sure which of these is in more widespread use. I think I see "icons" more, but I don't really pay much attention to the things so I'm not a good judge. What do people think?

Syndicated accounts/feeds
I'd propose using feeds where possible, and "feed account" where we need to differentiate between the account that gets created on site, and the actual source RSS/atom feed.

Voice Post/Phone Post
Won't be an issue when the site launches, since we won't have it (I believe), but we may as well figure out what we're going to call it when/if we do.
