Last week Andy and I were at WDCNZ  and gave a talk  in front of a
crowd of 150-200 web developers. It was very well received (especially
the demo ) and both Andy and I fielded lots of questions after the
talk. It was also live-blogged  on the Xero blog.
One designer even said to his colleagues that they should use Persona
for all of their sites :)
an interesting Twitter "discussion"  with an accessibility expert.
I talked to him afterwards and he recommended Knowbility  as a good
organization to hire to do user testing on users with a variety of
disabilities or assistive technologies.
The other thing he pointed out is that if we manage to make Persona
Section 508  compliant (which is basically a self-assessment based on
following the applicable guidelines), that could attract a number of
organizations in the US that are required to be 508 compliant and to
only use 508-compliant vendors in their user-facing products.
# Interested developers
I spoke to several folks were interested in trying it out for their
(proprietary) e-commerce sites. Many of those were looking at options
and were pleasantly surprised to see something so simple.
Andy also spoke to a few developers from SilverStripe afterwards who
seemed keen to add it to core (pending acceptance) so he'll follow-up
with them later. We both also spoke to a developer from Open
Polytechnic who could see great potential with using Persona internally.
# Questions from the audience
- Can we use it in mobile apps?
- Can we use BrowserID without the Mozilla branding?
- When will it be native in other browsers?
- What happens when users change their email address?
- How many people use Persona to log in every day? How many sites use it?
- What proportion of users pick Persona over Facebook when both are
- What happens when an identity provider goes down?
