Noticed the IKarmaYou application to Send Good Karma to friends on Facebook and have been playing with it for the last 4 or 5 days as I've been both getting and giving Good Karma's liberally.  I wrote my final opinion about Facebook Applications in The Analytics of Facebook (I'll often put my synthesis here). 

I was trying to find some stats for IKarmaYou and came across a post titled concerning the "good karma request" on facebook in Earth & Pragmatism blog where it's pointed out that:

"…But but: You can't give good karma. Or receive good karma. This is like requesting that other people send you a good body."

 Actually, Facebook gives stats on the IKarmaYou application:

"…59,067 daily active users 5% of total"

That's not bad (karma)!

Talking about Facebook Analytics - there's actually a site that can chart Applications against each other called Adomomics.  Here's some interesting factoids on Facebook Applications as of today:

• There are 849,142,168 installs across 16,192 apps on Facebook with over 200,000 developers currently evaluating the platform.
• These applications were used 34,175,797 times in the last 24 hours and have a combined valuation of $425,362,656.
• Facebook had approximately 68 million Unique Active Users in the past 30 days and a valuation of $20 billion.
• This translates to $300 per active user.

Did I read that right?  Each user on Facebook is worth, to advertisers, about 300 bucks.

Ask yourself what the average user is worth on each social network site?  How much would you spend, how much value, attention, is there to monetize?

I charted 3 Facebook Applications - Send Good Karma, Art of War Quotes and My  Personality.

 A couple of lessons here -

1. if you get a good valuation for your application - sell it quickly - as I'm not sure how long people will want to send Good Karma's to each other - I'm already getting tired of it and I've only been doing it for a couple of days.
2. Viral Applications are a pretty good way to introduce other content, like what I just wrote about in SocialRiots with the Bad Karma and Good Karma Series of Facebook

And here's the Viral Content that was pushed out today - a pretty good video if you ask me.
