But what is really happening on the site itself? When we spoke to Ello founder Paul Budnitz a couple of days ago, he said he didn’t know who Ello’s users are — the company doesn’t know user demographics because they don’t track them — and didn’t want to give specific user numbers, probably preferring for everyone to assume it was blowing up through the roof because that’s what the media was saying.
