[Testing] Which activity to test?

[Bob Clewell]

I'm a QA professional, I've got a G1G1 XO laptop and I'm interested in
giving some time to testing an Activity. I saw the testing matrix on
the wiki, and there seems to be a lot of activities out there that
need a primary testing volunteer, but it's unclear to me what
activities might have the highest priority.

Rather then randomly pick an Activity I was wondering if someone could
advise me as to where my time would be best spent.

Best regards,
Bob.
