As an example, my biggest issue with Twitter is the noise, which mostly stems from a single issue: people I follow don't only share interesting things, but they also share a lot of irrelevant stuff such as pictures from family hike. I'm sure this is interesting to some of their personal friends, but not to me. I want to subscribe to that person on a "coding" stream, and leave the "personal" stream alone. People are multi-dimensional beings with many orthogonal interests; Consider giving them multiple stdouts.
Also, I have to say, 140 is often too little :) Will you also force me to write up the occasional longer post on Google+ and then link to it?
This looks nice, I just hope you won't be a Twitter bare bones re-implementation that I have to pay for. Ideology gives you many points, but I'm not certain about just to what degree a sponsored tweet here and there really bothers me.
Though, in practice I don't think it would be as successful as you (and maybe I) hope. People who use twitter want to say something and they want to say it fast; they don't want to stop and think "is what I'm sharing (for example, iOS 6 download links when it comes out) code related, or related to Apple, or work?"...
It's times like this that I realize how much I take HN for granted. Great service. No Ads. Fantastic Community.
Even more important is the OStatus protocol, which if adopted, would allow decentralization and federation with other sites that speak the same protocol.
You all could be a revolutionary team, but as far as I can see the UI is not a revolution at all. I'm not telling you that a drastically innovative interface is needed, but to be future-proof you should go fully-digital, if not something farther.
The interface must be perfect, cool, useful, built tightly around the user and functions, not nice.
I hope you're not going to be flooded by a too common design...
Honestly I wasn't sure about Dalton's prospects at first -- but with the developer community hanging on to his every word, he might have a shot.
I still remember the days when Twitter was just a bunch of geeks tweeting about how much they hated MySpace. Now they can update their App.net statuses about how much they hate Facebook.
I definitely want to support entrepreneurs and App.net. But, quite frankly I don't see how they are going to build a user base.
But just having 10K people who want App.net successful is not enough to get me to put in $50 (or to even try it out for free).
Now, if this a community of a 100 entrepreneurs, I might be more interested. Perhaps, you guys need channels for various groups or something.
My point is that I cannot yet find an excuse to see why you will be successful and therefore would want to bet anything on you. Help me find that excuse :-)
