The potential of converting traffic into cash.
Let me explain and take Wazua.co.ke as a case study. Supposing 10,000 PERSONS log into wazua to check the free live data stream and an additional 40,000 guests do the same 5days in a week. Assuming that 1/3 the total visitors can pay a premium for a more live data streaming after a 10 day no strings attached period. The 2/3 who wont pay for anything can keep posting and directing traffic to the site while the paying 1/3 receive data depending on what they are paying for instance(First class - may be 100 vertical lines of trades, Business class (50) or Economy class(10) with the charges pegged on the service you receive.
That just an example...........

The problem is that many people here have internalised that Wazua is a free to air channel and has to transmit a signal as long as there is no black out.

Google plans to acquire a company known as Groupon for $6B. It is a tech start-up owned by a 30 year old that sells discount coupons through online media. The total investment in the company amounts to only about $140m. Even the international financial pundits don't get this math but Google insists the information about customer trends and patterns is what makes this company so valuable.

I wouldnt call it a bubble.The potential that those companies have is amazing.Look around,everyone is logged into facebook.Its just a matter of time before someone who has figured a way of converting such traffic into cash comes along and buys it.So why would you sell it for peanuts?The intangible goodwill is what makes it so expensive.

People who in to the cyber cafe to Facebook are either idlers or low end users. Its far much cheaper and time rating by login using my phone and only in to the cyber when I'm doing big volumes of data.

I see many Wazuans are being sucked into the madness as well! Any business owner can talk a good talk about potential earnings and what not, but as long as you have ZERO business(sales) like Twitter, then you are worth ZERO. OK, so consumer interest counts for something, but definitely not 4billion dollars!
As for Facebook hype, it also has to be understood that what they are trying to do is advertise to people during communication, which is very intrusive no matter how you spin it, which is why their CTR is so low despite the intense targeting of FB ads.
Bottom line is, its all hype till a company proves itself. Buy into the hype alone and you create a bubble; real money supporting cleverly disguised debt
