Hide/Show content with counts

I am interested to know what kind of entries/contents from my blog attract more reads…

I saw a blogsite Sinablog gets a relevant function (example: http://kafai200hk.mysinablog.com/index.php). Visitors need to click in order to read the whole entry, and there’s a counter for every entries to keep track of the no. of reads.

I found some hide/show plugins, but they do not get the counter. Does anyone know any plugin serving this function? Or any other ways/plugins to know the “no. of reads” of different entries?

Many thanks! Many many thanks!
