There have been a few issues, its not based on bitcoin so the wallet/node isn't exactly the same and so requires some interfacing, also as an anti-spam feature there is a PoW which can be taxing for the server when lots of transactions are occurring.

Finally there are some elements of the community who rely on the faucet as a way of life and so can get a little irate when things aren't smooth - the main reason that cryptopia dropped the coin - its not a reflection of the core of the community and there has been work to try and improve this generally. Raiblocks has a very different demographic to other cryptocurrencies - a social anthropologist would have a field day!

XRB is gathering steam, personally I'm focusing on developing usable webservices as hopefully that will create value. Working on integrating XRB with twitter to allow instant rewards for retweeting - check out @xrb_giveaway on twitter and if you want to try it out yourself you can use https://yapraiwallet.space and use the experimental twitter reward system to track your own tweets. The server will monitor a tweet and each unique retweet (where the twitter user includes a xrb address in their profile) it will then send them some xrb.

The exchanges will come - everyone is working towards that goal.
