It looks much better with line breaks, thanks ;)

I guess that means that your users have to be careful not to use the < and > characters, since you're not converting those to HTML entities either...

>> AndStatus Project:

“Regarding @MyNiceDisplayName - is it documented anywhere? I'm not very comfortable changing API based on "comments" :-)”

No, it's "documented" in observation. Just look at any client (including the web UI), and you'll see that the posts by "JohnDoe" have "JohnDoe" written somewhere, not "johnnydabest@johnserver.org" =)

Anywhere you look, you are "AndStatus Project", not "andstatus@identi.ca". The address is more like... "a detail", not something that's usually seen.

Also, this has nothing to do with any API. Adding @someaddress@someserver as part of the message is irrelevant. What matters is the metadata, the To and CC fields, not what names are in the message.
