Facebook has the potential to replace a lot more than just email.

Facebook could be the next Internet platform. One built upon interconnected social networks.

How about:

• classifieds (Craigslist)
• used and new products (Ebay)
• personalized start pages (Netvibes)
• social bookmarking (del.icio.us)
• video (YouTube)
• news aggregators (Digg)
• search engines, except the one inside Facebook

That scares me. Why? Because it’s a black hole – what goes in doesn’t come out.

Data is everything. If you own it (and have a LOT of it), you have a HUGE advantage. Just look at what Amazon can do with it’s recommendations.

Social networks, because of the network effect, are winner take all markets. Move everyone to the platform, build all of the apps on top, add trust, filter out all of the crap/spam, and you’re left with an Internet sized bundle of content with nothing but good stuff.

Which is wonderful, except the lock-in part. Facebook shouldn’t own all of the data built on top of it.

Do you trust Facebook?

I love these videos. Viral marketing made fun. Plus, host it on YouTube for free!
