Is it just me, or does this feel like linkbait? The facts seem to be accurate, but the style and the title make feels like a cheap shot to get attention to the article.
It would've been nice if OpenID provided a way for Web sites to contact users without knowing their email address. This way, the Web site owner will not to put up an annoying page asking for an email address, and the user has control over who's allowed to contact them through their settings with their OpenID provider.
Facebook is hopeing to be such provider and they're giving these nice features. There are a few Web sites that allow you to login to using your Facebook cridentials, and by doing so they can email you without knowing your email address. And, Facebook allows you to optout at any time and they also measure how many people opt out and put a cap on the offending Web sites if they start to spam people. It's a nice system, except for the vendor lockin part.
Looks nice. Being compatible with Blogger themes is a smart move. How do you plan to compete with Google Pages, Weebly, and all the other site builders? A calendar and a member directory might not be a big enough differentiator.
Don't touch the fonts. They're perfect. The bigger font gives the feeling of simplicity, don't lose that.
If you allow anonymous posting (and manage to control spam at the same time), you could have a winner. People hate to register to do a simple thing like asking or answering a question.
Brilliant. That's why Facebook is going to be one of the major web players soon. I can see them challanging Google in a few years. It'll be interesting to see Facebook's aggresive bully style head to head with Google's do no evil style.
