Well, blogs are actually useful. You can get to know and communicate with a person there, not like in various social networks. Of course, there are different blogs. Some have a goat with a perpetually trollish face, others have pop-up ads on the main page (for those without a paid account), and the rest are completely dead, for the most part (I'm talking about the Russian internet, of course). But that "one with ads" is actually quite good in other respects, for example. And it's easy to get used to it.
