Personally I find participating loyally within a herd helps build a character's reputation and notice, even if they aren't posting a lot. Lot's of herds have seasonal tasks which they love to see consistently completed, or various ranks which need filled by someone reliable, even if not always super active.
There've been a couple cases where not super active (in the sense of tons of posts or tons of hours spent onsite, but still /active/) characters have been recognized so its definitely doable!
