It's inconsistent right now. Sometimes they show up, and the next minute they don't.

My RSS feed off nitter.net has the complete text, no media.

I might be misreading what you're saying (and if so, apologies), but I just went to nitter.net and pulled up a couple of accounts and they worked fine.

Can confirm.

There were a bunch of commits yesterday, maybe there's a bug? Can still get account tweets on my private instance and haven't updated yet.
