You're right that the second sentence is simpler, but both of the sentences are in the active voice. (The difference between the two is in verb tense: the first sentence is in "present perfect" tense and the second sentence is in "simple present" tense. The first sentence places more emphasis on the writing as a completed action than the second sentence.)

A better example of the passive voice here is "A comment on HN was written by me".
