Social networks and blogs seem like a perfect fit. Yet, the merging of the two has been elusive.

Now, there may be solution: Tumblr. In fact, the company recently snagged $4.5 million in venture capital. The investors include: Union Square Ventures and Spark Capital.

True, it's not a big amount. Yet, it's still impressive in the current environment –in which investors are steering away from social media deals.

Interestingly enough, Tumblr doesn't even have any revenues. Oh, and the founder -- David Karp – is only 22 years old.

OK, so why the interest? Simply put, Tumblr has hit a nerve. Over the past 12 months, the site has hit 15 million monthly uniques and there are 500,000 users who are publishing on the platform. Keep in mind that the firm has only three employees.

For the most part, Tumblr is a simple application, which allows for the creation of so-called tumblelogs. Think of such things as short-form content, like pictures, videos and so on. It's easy to create tumblelogs (setup is only ten seconds) as well as to share them with your friends.

With the infusion of capital, Tumblr plans to make some important steps, such as adding premium products. And, assuming it's user base is loyal – which seems to be the case – there is likely to be some traction.
