I use a lot of comments, for many reasons.

While it leads to more things to read, which thus may take time, I feel that the benefits of using comments far outweighs the negative sides. This is even valid when comments are outdated usually. To me, adjusting and updating comments often was much easier and faster than describing something de-novo.

In the ruby land this is quite problematic because many do not use any comments. The result is a horrible code base. Getting people who wrote that code to use comments is often too late, as they already abandoned ruby in favour of another language, so I never buy the cop-out explanation of "the code is self-explanatory" - not even in ruby it is. Everyone can write horrible code.
