No, development isn't "off". There are some updates and fixes coming out of necessity (doesn't include the DEx), but our priority is indeed the startup that we are working on. We stated our own personal reasons for building this from the very beginning, it literally litters all of the announcement threads.

Regarding the DEx, it wasn't anticipated that it would be a problem to make it work, and we hope that we -- or someone else -- can eventually get it figured out. It's not like we don't want to have it. :-)

As for support, the best place to receive it is Skype or Reddit. Twitter is typically checked only when announcements etc are made, and I am hardly ever on bitcointalk at all. You can also email me @ w@hivewallet.com, but the other two seem to be more effective, since more people can see them.

Finally, if you are really concerned with Dogeparty being an independent success, I would encourage you all to jump in and help. For our part, we believe that the best way to make it a success is to build great projects on top of it. But I am totally down to help anyone who thinks otherwise and who wants to put time and focus into Dogeparty itself.
