Tumblr is a micro-blogging site and quite a popular one. According the their stats, they’ve had over 20million posts today – that’s a lot.

Last year, Sequoia Captial pumped quite a few $$$ into Tumblr (details of the amount are scarce). And I’m still not really sure how they expect to generate any money. On top of this, they’ve also recently had $5,000,000 thrown at them.

This is not a revolutionary question, but why the hell would anyone invest millions of dollars in to something that doesn’t make any money?

If we had $5,000,000 at PolkaSpots Supafly Wi-Fi, we’d be laughing – the things we could do. And we make money already!

Interestingly, as Tumblr has grown, their service has groaned under the demand with noticeable periods of downtime.

Growing a business from scratch is no easy thing, nor is creating a platform that’ll cope with future demand. Tumblr aren’t the only ones struggling to keep up – Posterous (their biggest competitor) suffered hours down a while back due to a distributed denial of service attack.

Someone asks me this at least 3 times a week…

Last weekend, I was asked if I had the Internet in my bag? At first I thought this was a joke but my friend was quite serious. Liz, the friend who asked this, is a Marie Curie Fellow at the University of Utrecht. Theoretical scientists are clearly insane – according to Liz’s website, her primary research interests are:

Multi-agent systems and the use of argumentation theory as a mechanism for dealing with inconsistencies that might occur either internally within an agent’s knowledge or between multiple agents.

I don’t really know what that means so I’ll stick with the Internet. I think she should probably stick with her argumentation theory…
