It's just not often for me to see that the later beats the former king, especially on the field of computing, where the former already establishes credibility and name to its users.
I do not have the tally to say that Facebook already beaten its competitors in terms of popularity and marginal number of users all over the world. But here in the Philippines, it is evidently seen that the tool/site is spreading like a wildfire.
This spoof site, where you could see both Philippine and International stars wind up together for some humorous content, just demonstrates how Facebook dominates the contest.
If you're a Filipino who wants to have a laugh trip you would definitely enjoy facebuko.com.
