The development has been glacial bordering on non-existent since launch on digg reader. The betaworks team that created it was able to do so in a matter of weeks– after re-writing and launching the new digg on a similar timeframe – which makes me think the current lack of progress is because they've moved on to other things (Instapaper, for one).

It's too bad, digg reader had a lot of promise.

I was a very happy Digg Reader user for a while, but the bugs just kept getting worse and worse, and I jumped ship.

Now I'm on BazQux, which works very, very well and very, very quickly, but has no mobile version and a design straight out of 1996.

And it's written in Haskell. Which makes me want to take a look at Haskell again :)

I thought they used Ur/Web.

Ur/Web is used mostly for generating JavaScript and part of web server. Most backend is written in Haskell.

I've been super happy with Digg Reader. The few bugs I've seen are not that big of a deal. I've never seen anything that an actual page reload didn't solve. I've not tried the mobile app though.
