IMPORTANT UPDATE: The person implicated in this post has vehemently denied involvement in this matter. Without complicating matters, I urge everyone to end speculation on this issue. Give all parties involved a break, lest feelings will be hurt. Also, before making any judgements, do take into account the implicated person's view in the

UPDATE 2: Here is another attempt at guessing Cloud's identity.

A mysterious person has been commenting in my Shoutbox under the pseudonym 'Cloud' for quite some time. All the while I was wondering about his (might be her) true identity when the name Cloud appeared.
The first time Cloud appeared was during the end of August.
Cloud I am new to here.I heard other people talked about your blog and so paid a visit. (2008-08-29 2:24 AM)
When asked who he was the first time, Cloud replied:
Cloud Ah ha.Cloud will pass by.See when I will reveal myself.Haha.Just kidding.Maybe some time I will tell you. (2008-09-01 1:14 PM)
Oh, he wants to keep it a secret... So fine, I left it at that. Cloud did not appear in my Shoutbox again... until last week.
Cloud Yaya.You haven't been updating for a long time.. (2008-12-01 11:50 PM)
Before that, I thought that Cloud had lost interest in my blog. When asked of his true identity the second time, he said:
Cloud Still haven't reach the time yet.By the way,chatting with a person you seem not to know.Doesn't it feels better?Though I know a little bit about you, (2008-12-02 5:10 PM)
Cloud I enjoy talking like this to you.Haha.Close yet far.. (2008-12-02 5:10 PM)
Then I asked: When is 'the time'? He replied:
Cloud haha.i also dunno..jz enjoy lo.not bad ma like this.. (2008-12-06 4:51 PM)
This guy really got me burning with curiosity. A la CSI, I found out that this guy is definitely from Nottingham University. Also, I assumed that this person has not commented on my blog using his real name before. And based on the way he speaks, I seriously considered him to be a girl. This got me racking my brains: Which girl in Nottingham reads my blog but never commented using her real name before? The result: Too many possibilities. I can't know each and everyone who visits my blog.
Then on Wednesday Sze Wei asked me via MSN whether I would like to know who is Cloud. 'Sure,' I said. She gave me two suspects; both of them seem absurd at first, as I haven't considered them before. Then she mentioned that the second person had done the same thing on her blog before. This got me down working. Based on the multiple visits of Cloud to my blog, the pattern corresponds exactly to that person!
Armed with that information, I can say with 99.98% surety (0.02% error in respect of the Heisenberg uncertainty principle) that Cloud is...
Benjamin ChangAuthor of DGSNice try, Ben! You would have had me stumped if you didn't impersonate as 'ying' on Sze Wei's blog!
P.S.: Thanks to Sze Wei for the lead!
