Facebook's killer app is here. No, it's Not places. (opens in new tab)

What scares me is the other week I sent a Facebook message that should have been an email, largely because a different friend in the same social circle had sent me a Facebook message on a similar subject.

It's really hard to use Facebook without it taking total control of your social interaction.

That was already fixed by the time Facebook came around. Hotmail was offering addresses that weren't tied to your uni or employer in 1996.

This is the main reason I always hear that people are 'forced' to stay on FB, even if they don't like it: so they can still get invited to parties.

> I actually read a fb message in my normal email box and if it's something actually valuable, ill then respond on FB

And that's the important bit, people seem to either check FB mail directly or read it in there own email. Either way you've got more chance of getting through to them soon if you send via Facebook... I don't like it either though, it makes me rather uncofortable to have more comunication going through FB.

Facebook didn't fix email with its Facebook 'mail', it did it with wall posts, comment conversations, and events.

Those can all be fixed easily enough. When (not if) facebook finally launches a full-featured email service, it will probably dominate gmail/yahoo/microsoft. You would get a address @fbmail.com or whatever so you could still use it as your "normal" free email client. But you then also get easy communication with all your friends, since facebook already knows how to contact them and can do so bypassing traditional email alltogether (since the messages stay entirely within facebook's data centers). Not to mention tying in to their existing products-If you got an event invitation (sent to your fbmail since you no longer check your gmail) it could show you all the details (no reason it couldn't do that right now) and which of your friends are going etc right in the email.

Most people have 'likes' that years ago were groups that were silently transmuted into pages by the group owners, and since then silently turned into public 'likes' by Facebook.

In other words, it's a very poor trust network, because no one is using it that way. Most people 'like' a lot of stuff in a casual or even joking manner.

Unlike, recommend, and complain might be useful, but Facebook is an advertising platform, not a recommendation engine. I doubt they'll make that transition, because it would cut in on their revenue to let people clearly mark advertisers as unwanted.

Facebook's increasing focus on business customers will be at the detriment of regular users, who will be demoted to the rank of mere 'consumers'. It's a subtle - but important - distinction.

Facebook's decision-making will increasingly be driven by thinking like "how can we monetize all this wealth of consumer data" or "how can we introduce tiered fanpage packages to business customers as a revenue stream" rather than focusing on what makes a great user experience.

Currently, knowing that my friend has achieved another 'badge' in Mafia Wars adds zero value to my life. It only gets worse as Facebook focuses more and more on business brands. What do I care if my friend 'likes' Apple or Nike? How does that improve my relationship with that person? People I am really friends with in real life don't care what brands I like, or what isotonic sports drink I drink. The like me because of me. Much as businesses would like to think that people define their lives by the products they buy (this is like the opening scenes in 'Fight Club' where Edward Norton's character tries to pick out stuff from an Ikea catalogue that defines himself) that's not a basis for a relationship. And Facebook used to be all about relationships. Now I look at my Live Stream...and it's got all this random flotsam floating downstream. I care about none of it.

The reason I love HN, incidentally, is because it's the polar opposite of MySpace and what Facebook is gradually becoming. Real people, that I share a lot in common with, expressing their real opinions, no auto-generated crap, and zero bling.

You see comments like "What could cause FB to die?" here on HN. They're so big at this stage, with the power of network effects and lock-in, that external competition is no threat to them realistically. The only way they will die is if they continue exactly the way they are now, making people's experience ever-more spam choked, till people realize "hey this experience is actually quite shit, even if I do have 500 online friends" and start looking for alternatives. We're not quite there yet though.

I've actually heard that it's also used by smaller businesses as a way to communicate with their target audience. So, for example, if you are a chain of cinemas, you can let everyone keep up with when/where you are going to release the next films. If you are a retailer, you can advertise when the new products are in.

A bit like they did in the past with email newsletters. (Though a lot better: for a start, it doesn't spam your inbox, which can remain for more important matters).

The contest-related stuff is a big reason, I suspect - I'm in a contest now with a team of people, where the team with the most "likes" clicked through them on to a company website is given an Ipad each (8 members). Believe me, we're doing a good job advertising the company for them :)

Not only that, but when people 'like' your product, they automatically market it to all of their friends.

They don't control the web though. So it's significant, but not as dire as the article implies it will be.

Except a major difference is Facebook has proven they are very talented and capable of making really well designed, easy to use and relatively bug free apps. Myspace could not even come close to pulling that off.

I've seen plenty of commercials with: facebook.com/myproduct as their URL. Crazy shit.
