I think that the bigger it grows, the less likelihood there is that the conversations that are on going are particularly interested to every random person who's just dropping in. And so when you open up the apand you see ten or so conversations going on, and yu're not interest in any of them, then the likelihood of staying with the ap is going to decrease. It also just feels like a very much a product of the pandemic. Now that things are starting to open up and people are able to participate in the economy in real life and in person, the popularity of these kinds perhaps might dwindle.
