It's somewhat hard to categorize Polish startup Flaker, and without playing around with it (it's in private beta at the moment), it's difficult to see how powerful it might be, but it's an interesting idea: take user activities on Web services and aggregate those into a profile.

Using public transports like RSS, it follows things like video or photo posts on YouTube and Flickr, or other activities in social networks, and creates a single place to track them all. Because this originated in Poland, many of the services are specific to that region, but this is just the beginning.

We talked to Adam Zygadlewicz about his new product, when it would be available, and how it works.
