Sorry to break it to you, Fortune 100, but when it comes to Twitter, most of you really, really suck. That's the primary takeaway from a study just released by Weber Shandwick showing that while many of you may tweet a good game, the vast majority of you may think you do, but you don't.

At most of the events I've been to lately, measurement continues to be a hot topic. The first question that comes up is, "What can I measure?" That's where this cheat sheet can come in handy: a list of 100 thought-starters.

It's tempting to say the best thing about the wine-tasting event Spit and Twit was the name, and maybe it was, but what made an even bigger impression was how social media is changing the nature of real-world events. It also showed the limitations of being digitally and physically social at once.

You may remember that a few weeks back, the Social Media Insider was a victim of paralyzing brain fog, on deadline, when she couldn't make any sense of all the social media information being thrown her way. While you're free to theorize that it was really writer's block, the experience led me to wonder, more than ever, what ways people are finding to filter social media streams well enough to derive quality from all of the often mind-numbing quantity.

Bankruptcies are hitting continuing-care retirement communities, which are designed to provide older adults with a home and health care through the final years of life.

The ways to access social content just increased by a factor of one -- a big one, with Microsoft's MSN.com announcing that it, too, will allow users to access their social nets from the MSN home page. While the news has certainly gotten the headlines that a portal with monthly traffic of 100 million warrants, in fact, MSN is the last of what used to be the portal world's Big Three to do so. In case you haven't noticed (ha! as if that were possible), Yahoo has transformed its home page into being all about Y!ou! AOL, meanwhile, has offered these features for a while.

Twitter just introduced Twitter Lists, the biggest change to its service that ever came from the top down, rather than from users or third parties. The best way to understand the feature is to try it out yourself, as it's rapidly rolling out if you check twitter.com. But I'll give you a taste of what it means for your day job, as well as your day-to-day Twitter usage.

I'm sitting at the 140 Conference in L.A. and have just finished listening to the CMO of Kodak and the VP of marketing for Virgin America talk about the value of their Twitter and social media usage. Kodak's Jeffrey Hayzlett explained how Kodak was able to name its new product based on suggestions from Twitter. Virgin America's Porter Gale shared several stories of how her company's social media usage helped retain existing customers. There's something missing, though: ROI.

Joseph Pecoraro details a multitude of the improvements he’s been making to the WebKit Inspector, with tons of new features for CSS, events, and DOM manipulation.

Here's something you don't see very often: the Social Media Insider staring at a blinking cursor, with no freakin' clue as to what the column should be about, five hours into the work day. I've trolled all of the usual sources looking for something to write about. But you know and I know that my lack of a topic was generated by something else: the information overload engine.

Android 2.0 Platform Highlights

Google releases Android 2.0 SDK:

Google has released the new developer SDK for Android 2.0 and notes that it now supports HTML5 features like SQL, App Cache, and geolocation—though I’m willing to bet there are even more WebKit enhancements under the hood. Go get the SDK and try it out yourself.

WebSaver:

A WebKit-based Mac OS X screensaver. Use any webpage or JavaScript program as a screensaver. Could be very cool use this in coordination with some of the Chrome Experiments.

“Microsoft has no choice but to make a leap of development faith, by abandoning the IE rendering engine and releasing new WebKit-based desktop and mobile browsers. IE is a dead platform.”

- Joe Wilcox, Microsoft should dig into the WebKit to stop Google from framing IE

Prices and plans design patterns:

Andy Clarke covers the design of a “Prices and Plans” page from concept to code and really demonstrates some great progressive enhancement using CSS3.

A preview of the unreleased and unofficially announced Verizon Droid phone with Google’s Android 2.0.

Google has released a developer preview of Chrome for Mac. It has it’s top tabs, runs on WebKit, and already supports themes. I’ve been running on it since Friday, and I can testify: it is one quick, minimal browser. Also love that it still has the WebKit Web Inspector, a major requirement for any web developer.

“Fast forward a couple years, and it seems Google’s done it.”

Microsoft is expected to announce that tweets and Facebook status updates will be searchable via Bing, expanding what we all perceived to be the potential audience for the inania that makes up our daily lives. Better yet, the deal is nonexclusive, which means, at any second, Google will be sifting through your boring life, too!.
