"Without continual grouth and progress, 

such words as improvement, achievement,

and success have no meaning."

Benjamin Franklin

Having a personal site is actual nowadays. As for me I think it is important to correspond to requiremets of one's life time. That is why having a personal site is useful and even necessary for modern teacher. But it has its own advantages and disadvantages. 

One of the main advantages is that a teacher can choose the most useful sites for his/her students and place them at personal site. Some students need more information than they can get at the lessons. So, a teacher can suggest them more information and exercises, on-line tests, sites for downloading, etc. 

But there is a disadvantage of lack of time. Another disadvantage is a difficulty of choosing sites that are really useful for students. More than that it is necessary to choose them not according to the educational information, but according to the ads they consist. 

Nevertheless, I think a modern teacher should have his/her personal site. The aim of it is to make his/her work more effective, to introduce the information about teacher's achievements and so on. So I for one who wants to have a personal site.
