Back in the summer, Union Square Ventures invested in a small financing for Tumblr along with some of our friends.

We didn’t blog about it because David Karp, the almost one man band behind Tumblr, has something new coming soon and he ideally wanted to announce everything to the world on the same day. Unfortunately when you make filings with the SEC, they get disclosed to the public and word leaks out. Which is what happened last week.

So what is Tumblr? It’s the next logical step in the blogging phenomenon. It allows you to blog quickly, easily, from your phone or your computer, it encourages reblogging and pulling content in from twitter, typepad, wordpress, blogger, flickr, delicious, last.fm, etc, etc.

I have a tumblog at fredwilson.vc which you may want to read instead of this one. You’ll get the same content there (or more) than you get on this blog.

Here are some more tumblogs that I like:

Bijan Sabet

Jakob Lodwick
Kevin Rose
Andrew Parker

And to highlight how much Andrew likes Tumblr, we asked him to write the Union Square Ventures blog post announcing the financing. Clearly it’s a bit anti-climactic since everyone found out about this deal last week. But Andrew does a great job explaining why we like Tumblr so much and I suggest you all go read it and leave us a comment.
