Recently I found out about Ping.sg by accident.
I realized that it has the potential and hence, I registered my blog and my development blog with it. I think it is so much better than Tomorrow.sg.
I realized that my site ranking in Alexa is higher than Ping.sg and Tomorrow.sg. LOL
lesterchan.net Alexa Rank: 23,774
Ping.sg Alexa Rank: 89,298
Tomorrow.sg Alexa Rank: 112,803
