HubPages is more of a place to post articles. It's not a blog where you post daily happenings.
You can see your Hub on your profile page. Viewers could see your Hub in any variety of ways. They can see it by going to your profile page, or if your Hub is listed on the sidebar of other Hubs as being related, they can click your Hub title there, or if they browse or do a search for your Hub topic they might find it that way. It depends.
