Not sure. Really depends on the the technology, price, adaptability, timeframe, etc.

All the current clients are “twitter” ish. I don’t want that at all. My work flow is totally different.

I want a hierarchical layout with a workflow style approach.

I other words, my typical flow is to go look at my followers first and see what they are talking about. I would want that organized by hash, and social graph. Currently it is manual and somewhat random.

Then if I want to reply, I just want to be able to quickly Tap to mark/queue for later.

Then I want to be able to reply with a list of previous notes just like you are showing, by working off my previous queue.

Then repeat but for whom I am following.

And possibly do the same for the universe based on a hash tag.
