I’m hooked. I’ve resisted for as long as I could, but I’ve fallen in-love.

I tried to resist all of the Facebook media love-fest for as long as possible. I remember reading about some crazy guy at Goldman Sachs or something like that who said that he’d rather get fired than give up using Facebook at work.

Last week, I read with some disbelief that Microsoft had valued Facebook at $15 billion, up from $10 billion just a few months ago, which makes Facebook the 5th most valuable Internet company in the world with a market cap that’s bigger than IAC and Salesforce combined.

Following is the chart from TechCrunch reviewing the market cap and revenues of the Internet giants. It’s unlikely that Facebook is generating the revenues to justify its entry into such elite status, but that’s not my problem. I’m a user, not an investor.

And after using Facebook, I can be a “hater” no longer. I find myself perusing my old computer for pics to upload, so convinced am I that the rest of the world wants to see pics of my weekends and holidays that I’ve long forgotten about.

I don’t have time to speak to my mom and she accuses me of avoiding her calls, but I look for pics of Xmas holidays so that I can remember the good times spent with her.

I also spend hours searching for “friends” with whom I’ve lost touch. Most of them I really never even spoke to in high school or college, and it’s been about 10 years since those glory days. But there’s a perverse thrill in re-establishing contact with people, some of whom you tried so hard to forget about when you graduated.

Maybe time heals all wounds.

Or maybe people are cooler and more interesting when you don’t have to speak with them. When all you have are photos and blurry recollections (or reimaginings) of good times spent together. When you can become a voyeur peering from the safety of your laptop into their lives and personal photos.

And then there are all those apps. I don’t think I ever realised that I needed any of them. A week ago I thought that the whole Facebook App Week, and the idea of VCs funding companies whose entire raison d’etre was to create a Facebook App, was ridiculous. And maybe they still are.

But like my iPod, my Blackberry and now Facebook, silly little things that shouldn’t matter so much now matter a lot and have become life-defining than interpersonal contact.

I’ve even started to use Twitter.
