Netspeak means speaking in ways commonly used to shorten words on the internet. It's becoming popular today and widely used by internet user especially teenagers. The reason is that they find it will be more convenient to speak in short forms, like saying "oh my god"as "omg". One more important reason is they think using netspeak is trendy.
I don't like using that is because I think that will affect the proficiency of English.(as my English is already poor....) I don't comment on whether its trendy or not, but i am sure there is no standard form of netspeak. If I want to express "you are smart boy" as "u r sb", but people may not understand "sb", or even get it as "stupid boy", then we need to spend time to explain it. It takes more time than just express it normally. Even I don't prefer using that, I know a lot of those terms as I meet them so frequently on sms, msn , facebook and etc.
