Tumblr Adds $25 Million in Funding

For a moment I thought that they'd just received more money, but it seems like it's just a confirmation of earlier rumours: http://news.ycombinator.com/item?id=1941227.

Anyone knows how they make (or plan to make) money? They don't put ads, and I don't see premium services offered at sign up?

This is their only attempt at making money that I know of: http://www.tumblr.com/themes/premium

You can also buy paid placement in their Directory tool (which is like a really nicely curated "suggested user to follow" dynamic).

Interesting. Although, it doesn't strike me as a scalable business. At least not to the point of justifying such big investment.

Current investors Spark and Union Square went in for $5M each and Sequoia took $20M.

Let's hope they spend it on some well needed server infrastructure.

Let's hope they spend it on finding a way to actually make money (other than receiving donations) so I can keep using Tumblr. I like it.

Will they use that money so that they can let readers post comments?
