Yappari has became the main reason for some community members to keep on using the N900 in the year 2016. At this moment I'm personally forced to use two different cellphone numbers, so I bought a N5 and installed sfdroid on top off SFO on it and start using it as a main device. The N900 is too much computer to be throwing away. I don't think it's a good idea to convince non-tech people to use Telegram since most off them like to make free phone calls for example.
