I have invested in Tumblr, the company co-founded by David Karp, who I recently had a chance to meet. Tumblr is a clever mix between Twitter, blogs and social networks like Facebook.

If we think of a blog as a diary, then a tumblr is similar to a collection of notes about interesting things found on the net or whatever else you might want to share with your friends (links, photos, videos, audio, text messages).

Not everybody has the time or interest to create and maintain a blog, yet with Tumblr anyone can create a simple and beautifully designed personal page to aggregate his digital identity and share content with their friends.

Tumblr can automatically import content from most of the Web 2.0 sharing services you use and show it as a continuous stream on your tumblr. When I shoot a photo with my unlocked iPhone, the iFlickr application automatically uploads it to Flickr and Tumblr shows it on my page, alongside my twitter and blog posts.

Tumblr has just released its 3.0 version with lots of new features and a stunning graphic design which also looks great on the iPhone.

This is a great idea. Adoption will be there… I’m sure the biggest question mark is execution.

The only thing I would change is adding a line or two on the home page what Tumblr does. This domain could see a lot of type in traffic that is mis-spelled and result in new customers, but, kinda of hard to sell your self if you don’t tell someone what you are offering.

It looks great! I think Gustavo is right. I am looking at this for the first time, and although I can see the point of it, it doesn’t explain clearly what it is actually for on the home page. I think it should say something like ‘Tumblr is your online scrapbook …’
