Recently, Yandex launched an internal web messenger for its wow.ya.ru. In this regard, I again climbed to play with xmpp.yandex.ru (when it first appeared, I connected it and, as unnecessary, left alone).
Firstly, there is integration with a web messenger - it receives and sends messages. But only in online status, for some reason, although it may be that this is my own glitch. And secondly, the online status message automatically rushes to the site as a “mood”. Which is very similar to the well-known Twitter.
All this again suggests thoughts about Yandex and messengers.
