Don't abuse it though, it will backfire. For instance, writing technical articles about Apple generally does well, but I see many writers abusing it and then either getting ripped to shreds in the comments and losing followers or just getting ignored because it's too much of the same stuff all the time. I for instance try and keep to max 5-7 Apple-related articles a month on average. Sure, there are peaks when new stuff gets launched but otherwise I keep it to a lowish number so I bring genuinely new content and perspective and don't risk repeating myself.
