Made it to Techcrunch with the Virgle.com domain: “Virgle.com - how Google and Virgin forgot a domain“. I wonder how this story will develop. Will post updates here.

UPDATE: Virgle&Google ‘not amused’ with Techcrunch coverage. Caspar Wenckebach steps in to prevent me from saying stupid things.

Someone once told me that there are two happy moment in the life of a boat owner: the day he buys his boat and the day he sells it. The rest is spent fixing, moving, cleaning and worrying about the boat.

I noticed that most real-estate websites concentrate on these two moments (buy & sell) when it comes to home owners. All these websites try to make money when people want to buy or sell their house. That means that most people rarely need them.

My upstairs neighbors just sold their house. The price they got per square meter (€4191) means that my house almost doubled in value since we bought it 7 years ago. I hadn’t thought about that until my neighbors sold their house and I recalculated the value.

So that got me thinking. Could it be possible to build a service that appeals to home owners and keeps them up-to-date on the value of their house, what similar houses in the neighborhood get sold for, what their over-allowance is and if they can’t get a better mortgage based on the value of their house and the current interest rates.

There are a few variables that make it hard to predict the value of real-estate. But I’m just suggesting that we really predict values only based on square meters. What i would propose is that we take the last known valuation (you bought the house for how much?) and take that as a the basis. Then we look at what other houses in your area get sold for and based on that we could multiply the value of your house.

My guess (but I’m not that good with math so that is why this is an OpenIdea) is that the more houses are added to the database the more precise it will be able to predict the value of a house.

There will always be exceptions and factors that will influence the price of your house positively or negatively but those could be added as we find out about them. Lets say you buy a few extra square meters of garden or you find out that your roof is leaking. In the database you could say ‘Shape of building: needs work” which we could translate into “needs work = 5% off value”. A bigger garden would be “Square meters x average garden value + total value”.

I can image that if you have the last 6 transactions of a house and the houses around it, the current interest rates and a few more variables you could give people a pretty good estimate of the value of their houses.

I registered the domain name Taxati.com for this OpenIdea. In The Netherlands a ‘taxatie’ means ‘Appraisal’.

Although the math behind the calculations will be pretty complicated in the long term the basic system should be easy to build. People should be able to input a few values and their contact data and then we could send them a weekly update on the value of their house, including a few interesting deals to re-insure, re-mortgage or maybe just sell their houses.

Who wants to help me build it?

This Sunday Ernst-Jan and I will get on a plane, sleep for 11 hours, and then wake up in San Francisco. We will attend the O’Reilly Web2Expo and every party we can talk our way into. We will be staying at the Handlery Union Square Hotel

Our itinerary on Tripit.com

You can follow our itinerary on Tripit.com. In fact; I invited so many people to my TripIt account (via the one-click LinkedIn import) that a few days ago I could crash the TripIt server just by visiting my profile. This what the Tripit helpdesk mailed some of my friends:

Apparently, someone you know was so gung-ho about TripIt that he started inviting all his friends. :) This seems to be causing real performance issues for the invitees and him.

Forget about the Digg effect, here comes the Boris effect!

Is it Blogable or Bloggable?

To do a little promotion for The Next Web Blog we decided to print some stickers. I made a few drafts and asked everyone in the office to pick out the best one. Everybody liked the “This object has been marked: BLOGABLE” one so I ordered 1000 of those. Then when they arrived someone asked me “Isn’t Blogable spelled with two Gs?”.

Oops…

Since then I have talked to a lot of people and have googled the issue extensively. The consensus seems to be that Bloggable should be spelled with two Gs. Fortunately for me even native english speakers seem divided on the issue so I think I will get away with it. People who don’t notice the spelling error won’t mind. People who do notice it have an extra reason to remember it.

Parties and events:

Here is a list of all the parties and events we are planning to visit. Have an interesting start-up that should be featured on our blog? Don’t hesitate to approach us and tell us all about it. Read the rest of this entry »

Dutch social network received a large investment yesterday. They couldn’t find the founders so the Dutch evening news decided to visit The Next Web Conference and ask a few influential Internet experts their opinion. Guess who they found… ;-)

Good NOS quality version:

Lousy quality Youtube version:

We are extremely busy with The Next Web Conference 2008 but that doesn’t mean we don’t work on our other projects too. If you feel lucky you might want to play around with our new and improved Fleck.com service. Officially in beta at http://beta3.fleck.com/

Kevin Rose has promised to grow mustache for the Amsterdam Diggnation show. He just posted that on pownce (“Finished taping Diggnation — Alex and I agreed to grow mustaches for the Amsterdam show… damn it, what have I gotten myself into… ”).

We decided to follow their example. Here is a preview of what you can expect:

Going to the conference too? Grow your mustache too or bring a fake one.
