Evaluation of your blogging experience

In general the experience of writing blogs is a methodology adapted to the current times with the classic purpose of the student to write and improve their grammar in English. Although this methodology is effective, it fails to capture the total attention of the student, since when occupying computers is lost contact with the teacher, which can guide you and tell you what mistakes you make, this in the communicative aspect.
Another purpose that I do not understand much is the issue of the number of words to be used, I feel that some topics are not so extensive as to use more than 170 words.
The system of "blogs" is just beginning, it does not take many years, taking into account this time it is observed that it has been a good method of study and preparation.
As a suggestion of some topic, I would like to see topics such as the situation of some countries, opinions about some news or some topic on some scientific or artistic subject. Particularly the subject of which would write would be related to conspiracies or with some sense of political or administrative complaint, it may be interesting to us but it can be funny and capable of generating diverse opinions.
