It seems somehow a long time passed by that I didn't make a new post here. The reason is very simple: the iPhone.
Since I've used the iPhone around 2009, it is always a tough job for me to post something on blogger.
There are many apps on iPhone which can do the communication well, such as twitter, Facebook and so on. But until today Google gets the blogger app on the iPhone. So I think it may be already too late for such service from google. Anyway, I will try to update my blog here from today :-)
