I can appreciate that OmniGroup has several software offerings and that they can't only focus on OmniFocus. And I have witnessed that they are improving OmniFocus with each update. (I've used both OF for the Mac and iPhone since they were released).
However, I do agree that at times it seems as if the development process is very slow. For example I'd like to reference a problem with auto-completing projects duplicating themselves that has been discussed on the Forums since May of 2009:

Before you ask, yes I have submitted this to Omni and not just discussed this on the Forum. I first sent this problem to Omni on May 4, 2009.
As you can see, it was determined that this in fact is a bug and is slated to be fixed in version 1.8. On January 12, 2010, Brian officially stated that it was going to be fixed. Well, here we are on April 8, 2010 and version 1.8 still isn't out (as a stable release) and the bug still has not been fixed. I understand that they temporarily shifted programming resources to the iPad release. However, it has left many of us with a feeling that OF has been abandoned (at least temporarily).
(Some of you might suggest that I download and use the 1.8 Sneaky Peek. However, as the data in my OF file is crucial to my working life, I am unwilling to risk damaging or corrupting it. I have learned the hard way in the past to wait for a stable release of updates of all software).
I think communication helps. But ultimately, timely delivery of software that is trustworthy is what is needed.
