While there are plenty of groups around for specific languages (PHP, Ruby, Javascript) there's no group around the hub dedicated to the discussion of experience-based best-practices on the ridiculous number of things front-end web developers need to master to be at the top of their game:

• HTML5
• CSS3
• Cross-browser Support
• Grids, Design basic
• CMS's
• Mobile support
• JavaScript
• jQuery
• Performance Optimization
• Conversion Tracking
• A/B Testing

...AJAX, JSON, OpenGraph, RDF, and on and on and on...

Join up and let's learn and stay ahead of the Web curve together!

Note: this a group aimed more at experienced front-end developers who want to learn about the technical details and best practices of current and next generation technologies, it's not necessarily aimed at beginners to the web (though all are welcome)
