Libra has been the most hyped, when telegram was introduced it doesn't get much attention in the media and in the crypto community like libra did, personally i will give it to libra. it got attention of a lot people.
but now the project is really releasing products that are useful for everyone. Now Facebook with Libra even supports big companies behind them. obviously that makes everyone talk about it. No need to be surprised, we just look at how markets and communities try them.
