It’s funny, I have always been a believer in long form video. Heck, today I put up a 30 minute video with the hottest mobile social network’s CEO (Bluepulse).

But why is YouTube going longform, which is what Silicon Alley Insider just reported?

Easy: it’s much tougher to monetize short videos of, say, kids doing skateboard tricks, than it is to put some ads into a long video like the ones I do at FastCompany.tv.

Advertisers also will pay a lot higher rates for those long-form ads.

Why?

Because someone who’ll watch a 30-minute video is HIGHLY ENGAGED. They are far more likely to become a customer than someone who just watches a two-minute entertaining video.

Here’s why: long videos are a filter. Only the most passionate and most interested people online will watch such a video. Those who aren’t interested wouldn’t even consider watching a long video.

Think about the video I just put up. I bet that out of the tens of thousands of people who read this post over the next day or so that only 5% will be interested in the topic of mobile social networks.

But, if you ARE interested enough in mobile social networks to spend 30 minutes to learn more, think about what that says and the liklihood that such a viewer will be responsive to advertisments, especially ones that are contextual. Imagine that another company building something for mobile users, like Brightkite, put an ad in that video. If you spent 30 minutes interested in mobile social networks, wouldn’t you spend 15 seconds hearing about a new mobile tool that’d add onto Bluepulse? You sure would (at least in aggregate).

But, what kind of audience would show up on a skateboarding video? How likely would they be interested in hearing about Brightkite? Not nearly as much.

So, as an advertiser, which one would you rather spend money on?

Longform wins and wins big.

Oh, and don’t even start thinking about the buying process. If you do, you’ll see why Gary Vaynerchuk is the most brilliant marketer out there right now for starting Wine Library TV. I’m going to do a whole post soon just on what Gary is getting that even Google and Facebook aren’t getting.

Oh #2. Mark Cuban basically just posted the same thing I did, but comes at it from a different angle.

Several months ago Andrew Feinberg, founder of the Capitol Valley.net blog, laid down a challenge to me and other tech bloggers: why don’t we ever come to Washington D.C. to get the politicians’ view of the tech industry?

After all, politicians have huge control over our industry.

They can decide things concerning network neutrality, taxation, whether universities get funded so that our industry will have a constant stream of new potential new employees, immigration (one tech-industry CEO recently told me his company is losing its best R&D talent which we educated here, but then are forced to go back home due to immigration laws), wireless bandwidth allocation, and much much more.

These are issues that the “shiny new thing chasers” like me don’t often talk about cause, well, they require doing homework and building partnerships and, well, going to Washington DC. Most of the geeks I hang out with don’t like hanging out with politicians. They would rather watch an hour-long-PowerPoint presentation on some boring enterprise-focused technology than hang out with politicians.

But I saw value in Andrew’s plea. He was right that we need a new conversation about technology and politics, particularly because there will be a regime change in Washington DC in January (even McCain would bring a different approach to the tech industry than Bush had).

So, next week me and the crew from FastCompany.tv is headed to New York for a day to attend the Personal Democracy Forum. Andrew will do some interviews there with me and I’ll be on a panel discussion.

Then on Tuesday we’re headed to Washington DC. Right now we’re tentatively speaking to four congressmen/women including Nancy Pelosi, speaker of the house.

My agenda for the week?

1. Learn about pending or upcoming legislation that will affect the technology industry.
2. Start a dialog between tech journalists and politician’s staffs, so we will have better understanding of what they are thinking and will have a chance to get our audiences feedback on potential legislation.
3. Hear how the regime change (er, Presidential election) will affect what they are thinking and what executives at technology companies should be aware of going into 2009.
4. Listen and bring you into conversations. I hope to do some Qik videos while there, and have some discussions on Twitter and FriendFeed.

Andrew also has us scheduled to interview a few key members of the FCC and we’re still working on our schedules to fit in some other fun stuff.

Plus, on Wednesday night we’re hosting a party which is open to all — wow, 122 are already signed up on the Facebook page for the party. We’re hosting Gary Vaynerchuk, the web superstar behind Wine Library TV and owner of one of the biggest wine stores in the world, along with a few other surprises.

Anyway, I really want to thank Andrew Feinberg. He did all the heavy lifting on this week and it should be an amazing week. He has my deepest respect and can’t wait to see what conversations start.

We’ll publish our calendars as we get them firmed up. Unfortunately in the world of politics even the best planned out calendar can instantly change due to world events, so we probably won’t know for sure we’ll get interviews with specific people until it happens.

Anyway, anything you’d like us to look into while we’re there? Leave suggestions on the comments here.
