m.verkkokauppa.com uses Bacon at the moment of writing this. It is so awful that I wrote an article about Bacon's lack of performance. I wouldn't recommend anyone to use Bacon for anything serious.
I assume people who used it got excited about it initially a whole lot and now that they've seen what it is remain silent as they are shamed of ever getting excited about it. But that is just a guess and not based on any facts. The truth is there is very little anything on the web about Bacon so it is probably best to just ignore it.
Kefir seems like a better one if functional paradigm is close to somebody's heart, but I haven't used it yet to see whether it is really any good.
