Just a small announcement. We have opened up the API for 30 Boxes. My hunch is that it will start slowly and gather a lot of momentum.

Very exciting.

Any and all developers, start creating!

I guess it is some sign of success that there is already squatting going on for domain names similar to 30boxes. Some company going by 86 Systems has gobbled up the numbers 28,29 and 31.

Have a look at the whois for 28boxes.com, registered 5 days ago!

Techcrunch #5 was even bigger than #3 — nearly 400 people on about as miserable a day as you can find in Northern California.

Lots of recap on the event from the big bloghonchos in attendance: Arrington, Scoble, Clavier, Winer, and many more. Scoble and Shel Israel signed their new book, Naked Conversations, for hours on end — banking a lot more than AdSense would generate.

Fairly incredible that an innocent backyard bbq could morph into a massive new media juggernaut.

I am not buying into the bubble theory. There is a subtle shift going on and it is creativity that is at a premium. Web2.0 may have been twisted into a marketing meme, but there is some real collaboration and sharing going on. Reminds me of the pre-Web1.0 days when people wanted to “swap links.” Now it is about having applications play together which is following the script to a tee, but it is very real. I had Chris Messina from Flock extolling microformats, Leonard Lin of upcoming.org offering to make sure his feeds function well in 30boxes, and Dudley Carr of gtalkr talk to me about our apps playing together, all in the span of 10 minutes.

Joel on Software recently lumped and panned a lot of the new calendar apps. He’s entitled to his own opinion. I just take issue with the lack of thoroughness with which some people approach writing articles.

Joel, if you had taken a look at some of the information that was out there about 30 Boxes, you would have seen that we are outspoken about erring on the side of simplicity. There is a massive market of people who have yet to form calendar habits and/or are simply frustrated with the Outlook paradigm.

And trust me, your “needs” are on the absolute highest end of features, and we explicitly set out not to design this calendar for you.

I am sorry you won’t be paying attention to 30B as it grows. So far, we are quite encouraged: with 18,000 users signed up in the first 10 days, a full 35% of those have visited the site in the last 24 hours. With our forthcoming API, we are confident that there will be applications built on top of 30B that take calendaring to unforseen and exciting places.

One more thing, we didn’t build this calendar for Yahoo! Scoble and Jeff Clavier (who has posted about what we really are up to) take the time to get to know the people putting out products before making assumptions on their business objectives.

Anyway, when assessing your criticisms we are going to take your advice: “You don’t build a product for one customer. It’s just too risky.” ;-)

After far too much hype we turned 30 Boxes live today. This little clip about sums it up. Requires Quicktime with the H264 codec, so if you get an error or can’t see anything. Go download it. Play Video.

With 2000 new users in the first couple of hours, smart money says the site is going down tomorrow. We still have a lot to do.

30B Blog is now open as well.

We had an informal session on calendaring yesterday. Tom Hawk has a lengthy (and flattering) write-up. Digg it!
