Oh..whoops. I suppose "working memory (machines)" is an analogy to "working memory (humans)", so your use of "working memory" actually directly refers to humans, and isn't an analogy at all :)
If your product is a mobile app primarily, domain names are far less important. (We don't own bump dot com, and while it's hard to prove the absence of a thing, we don't think it hurts us at all).
Hi all, this is Dave, CEO of Bump (we make Flock). Just saw this thread, and though I've personally emailed with wdr1 already, I wanted to give everyone here the details.
These are not automated text messages coming from our servers. And they are not automated invites sent on behalf of users when they sign up for Flock. They are intentional invitations sent directly by a real user.
The flow is:
1) User navigates to the Invite Friends page
2) User sees all her friends in her address book on her iPhone and taps on the ones she wishes to invite (phone numbers are shown below each friend)
3) User taps "Invite" button
4) User is taken to the native SMS UI with the contacts she chose in the To: field, which is editable, along with the link to download Flock, again, which is editable.
5) User must press "Send" on the SMS UI to send text messages to those friends.
We've tried to make this flow as explicit and intentional as possible while giving existing Flock users a tool to invite their friends to use the app as well.
If there are examples of apps that do this better than we do, we'd love to hear about them so we can improve the flow.
Work on the 7th most popular mobile app of all time with more than 50 million downloads. A hint of some of the new things we're working on: http://bu.mp/labs
We make Bump, one of the top 10 mobile apps of all time, which we're using to let you do lots of stuff in the physical world with people, places, and things around you.
