No, I don't consider the hub score. It's not an objective tool to use for evaluating someone's writing. A great hub can come from someone with a low hub score.
I look at topic first. A title is important to me, something I've had to learn more about for writing my own hubs. Even if I don't have a particular interest in the topic, a good title can peak my interest and if the topic is handled well from the beginning, I will almost always read it all and comment.
I do have some favorite topics that I like to look for, but even then the title can make or break whether I read it. Still, if I'm particularly interested in a topic I'll read through the hub to glean what I can though it may not be well-done.
Even if the hub isn't a great one, the hubber might be teachable. I know I am grateful for good writers who read my work, thereby giving me a chance to read theirs and thus learn to improve my own web-writing.
