This morning newsblur asked me to choose between a limited free account and a subscription, so I decided to subscribe for $12 per year and went through the paypal process, which said it worked. However when I was returned to newsblur, it again showed me the screen asking for money or to turn on the free account. I closed that tab and opened a new tab to newsblur.com and saw the same thing.
Luckily I had an email from newsblur when I set up my account, so I could see that they have support via Get Satisfaction.
