Pepsi Refresh Project logo* Len Kendall and Daniel Honigman launched an interesting collaborative blog on New Year’s Day: the3six5’s posterous. Here’s how they describe it:

“Every day for 365 days, a different person will write an entry about their experience that day. It doesn’t have to be about a specific topic, the key is that it somehow relates to what is happening in the world that day and how it relates to them.”

There are still some open dates for contributors later in the year, and I hope to snag one.

* The imaginative Pepsi Refresh Project starts accepting submissions tomorrow. If you have an idea to help your community, it could be worth as much as $250,000. Certainly worth brainstorming about.

* Speaking of brainstorming, that’s what I’m doing this week and next for a possible mega Social Media Breakfast gathering at this March’s SXSW Interactive. For one of the world’s biggest gatherings of innovators, geeks, entrepreneurs, and practitioners, I’d like to think we can organize a thought-provoking event to move the social media industry forward. Stay tuned.

* I’m not the only one dreaming big for SXSWi. Austin pal Tim Walker is considering a pep rally–a pep rally!–for his session on social media and sports. I’ll bring the bullhorn.

* Is open online collaboration and crowdsourcing putting a damper on innovation and turning our brains into “World Wide Mush“? Mitch Joel considers the question.

* Just how drastic was the digital advance for consumers in the recently concluded decade? Forrester’s Josh Bernoff has the numbers. (Disclosure: My employer, LiveWorld, is a former Forrester client).

* If 2010 is indeed the Year of Mobile, then ensuring your website is mobile-friendly should be near or at the top of your to-do list. Stumped on how to get started down that path? The Online Marketing Blog has a post with 9 good tips.
