When you first start your account, you should have four apps pre-installed. These apps should be renamed to demonstrate that they are the "demo" versions of the apps.
Masonry = DEMO Photos App
Linkalatte = DEMO Links App
Hello Places = DEMO Places App
Basic Contacts = DEMO Contacts App
What the account holder sees when they arrive at their account for the first time:
If we're only picking one demo photos app to start with, should it be masonry or timeline?
Masonry (I wrote them all in the issue description above.)
Doh, precoffee brain on that one ;)
