In case you aren’t already persuaded that the Live Mesh team are a bunch of L337 H4x0rZ, check out the ids of entries in the Profiles feed.
I believe this also demonstrates their far-reaching commitment to open web standards and the new generation of social apps. Or perhaps the hidden message is “so easy, even script kiddies can hack it!”
You can see this for yourself by firing up the Live Framework Resource Browser (LivefxResourceBrowser.exe from the SDK tools) and drilling down into Cloud LOE > Profiles.
On a slightly related note, as I was digging around with the Resource Browser I discovered that the following two URL styles appear to be interchangeable.
I’m not sure if the email identifier format is stable enough to bank on, but it’s convenient for typing or tweaking URLs by hand. Does anyone know of other equivalent identifier types in Mesh resources?
