The reason for this is imo, that Dash promised a lot and a lot of projects started, but one has the impression that none of those really found it's end.
For instance darkmixing. For how long now is this feature available now? A year? Recently i used it for the first time and was SO dissapointed. It took me 2 (!) days to mix 1000 coins. Unbelievable! Who do expect to use that stuff when everything takes so long? I know its a solvable issue. But ffs its been a year now! Same goes for masternode blinding etc.
You got to finish things first before moving ahead and open new projects.

That's a fair observation. DarkSend is production-ready and working, but liquidity remains a problem. I think Evolution is going to make privacy issues much easier. It appears to support Dash 'bills', where 0.1 1, 10, 100 DASH denominations are passed around via stealth addresses. Once you've broken up the Dash units into these denominations, re-mixing should not be needed.
