This isn't so much a column, I suppose, as it is a meditation. It's the kind of column -- er, meditation ---that I write when I've been spending the week on Cape Cod, alone with my daughter, strolling out at low tide against a limitless sky, and, where the only tweeting is coming from actual, physical birds.

On July 2, 2004, I penned a Search Insider column for MediaPost that quoted Dr. Seuss and Eminem, followed it up 18 days later with a biblical allegory about search engine optimization, and nearly every week since then, I contributed to an oeuvre here that ultimately numbered 400 editions. So as not to bury the lede, this is my final Insider edition - at least for now.

Yesterday was a pretty interesting day here at the Social Media Insider Summit. It's not every day that you get to hear an executive walk through the social media efforts of the Obama campaign, have another predict the demise of the Facebook "Like," and also debate whether tablets really should be part of the mobile category at all, or thought about as their own ecosystem.

Facebook has earned a few degrees since it launched as Thefacebook in 2004. A Facebook media kit from the spring of 2004 recently surfaced, and it offers a glimpse as to how much has changed since then. Here are 10 quotes from the media kit that illustrate what has changed with Facebook, media, and online advertising.

There are times when I'm sure we've gotten this Facebook thing -- and maybe this social media thing -- all wrong. When it comes to the Facebook IPO, yesterday was a day like any other day. Well, perhaps it was even more of a day like any other, because there was a clear, mathematical reason the stock dropped: the first lockup expired. This, of course, means that the Interwebs are full of almost gleeful headlines about Facebook's crash-and-burn:

One morning, I arrived at work to find an unexpected visitor waiting for me at my desk. Short and bald, he was shirtless and wearing the most extraordinary pair of pants. He goes by the name Agent 011, but his real name is Chester Chickenpants, and he may be your next social media role model.

News Flash: Facebook marketing works! Just ask Marc Pritchard, Procter & Gamble's global brand building officer (love the title!), who just told a rival publication that Facebook (and Yahoo) were "fundamental" in an interview about the company's ubiquitous "Thank You, Mom" Olympic campaign.

Consumers have embraced social media, with channels such as Facebook, Twitter, LinkedIn, Pinterest, Google+ and the like having become the preferred gateways to access personal and professional information. These platforms have reduced the friction in how consumers can share, consume, create and purchase products. In addition to the big five social networks, nearly every website has social features integrated into a brand's owned channels, such as consumer product reviews, social referrals, social sharing features and feeds from social network channels to name just a few.

Sorry to be posting the column so late this week, but I've been busy working on this great app idea. It's called Spoiler Alert, and it promises to wipe any breaking news about who won the 200 IM at the Olympics from every aspect of my life until I'm good and ready. It'll monitor Twitter, the front page of nytimes.com, NPR News, while I'm indulging my carpooling hobby, you name it. I can't wait to inhabit this beautiful bubble this app will create, and I bet you can't wait, either.
