it would be nice to have riot.im added to the list of available messenger. Because it has a web application, this should not be problematic, but it could be very useful for people who care about their privacy as riot.im seems to be one of the most privacy-oriented and most polished open source messaging apps out there.

Moreover riot.im is used mostly by so called "power users" and (at least this is case in Poland) Opera is used by power users as well.
