I've been trying to write three every two days. Also, I try to spend about an hour a day reading 3-5 hubs of each of the most recent 5 hub-posters. I go to view hubs sort by latest, pick the most recent one, read that hub and ten 2-4 more from that hubber, then I go back to hubsm the latest, pick the second most recent and do the same thing. Continue until about an hour has passed. This has brought more people to my hubs and has raised my score.
