Dear Wong,
Sorry that i've deleted your last paragraph of information, it was nothing personal.
The point is that on this site when you are citing information it's better for you to have the sources properly cited. This means that it would be better if you can add a link to the source of where you've obtained your information.
Apart from that would you mind adding more neutrality for the parts that you've contributed?
Here are some practical suggestions:
In a review (what review? sources or link?), SINA.com reveals their business status. Many are stunned to know the impact of SARS on SINA.com (any data to support this?). While other businesses were heavily struck by the SARS, sina was, and has been,thriving. By July,2003, SINA.com has 421 online advertisers (sources). Though, this number remained stagnant during the SARS outbreak, their advertising budget were mounting higher (source). Also, owing to the fear against SARS, people stayed, much of their time, at home and surfed on the net, boosting the online advertising and the use of short message services(SMS)(what does SMS has to do with Sina.com?). SMS then became a proven cash-cow for Internet portals. (Can you add a link here if you've read and obtain the information online?)
Hope that you don't mind about the suggestions that I've made. Again I was sorry for deleting the information directly - if I knew earlier that i can email to you via this first I would have emailed you instead of being that adrupt. Thanks very much for everything. Please feel free to let me know in case you think that I have problems too.
All the best.
