I thought it has a lot of interesting ideas. Although much of them can be emulated by any other platform, if BB proves to continue innovation especially in the business/corporate sector it could gather quite a following.
I once lost a domain for clicking by accident the 'delete' button. I sent them an email asking then to undelete the domain since it was an accident, got no response. I don't know why a feature to delete your domain was so easily accessible.
I thought you were going to say you taught your children programming by creating algorithms visually through blocks. Otherwise they are pretending to be having fun.
I agree that app.net is an awkward name, but you're wrong about it not being about apps: It's developed explicitly as a platform on top of which apps can be built. Hence the File API.
The Twitter-like interface you see when going to the site is Alpha, an app built on top of the app.net services. Similarly there are apps like Patter which go in other directions, creating an IRC-like environment.
are you kidding ? users will never pay for twitter or facebook. As soon as facebook/twitter is a paid service people will leave it and find for alternatives.
For paid APIs that's a different story but nothing is eternal on the internet.
If payment is made mandatory for those apps, it'll kill them. But making payment an option that enables more features or services would be a great business model for them (and less prone to backlash than selling users' privacy or plastering your site with intrusive ads).
i returned to ubuntu and I'm pretty happy with it. it lets you have the kind of system you want while taking care of stuff that's usually a burden to set up
