I stay a long time, between two and eight hours ... huge. Causes: I try to interact with as many as possible, I have to read, I comment. Then I have to write, select photos, translate, check the translation ... my problem is that I use English from memory, I try hard not to make grammatical or word mistakes. This is a big time consumer.
Unfortunately, the results are not proportional to the effort so I will reduce much of the activity. I will make smaller and rarer posts.
