To get word out when you create hubs you need to consider the following:
follow more people so that they'll follow you, it works this way-when you create hubs, by default hubpages sends an email alert to all your followers to go see the hub at the url posted.
If you have many fb friends and twitter followers, take a step further and tweet this hub, and include it on your fb wall.
If you create hubs always include the rss feeds capsule, to highlight your older hubs.
Also on rss, create a tag on a category-for example if you have hubs on "Horse Shoes" create a tag on horse shoes with your username to make it more unique-like "chinemeremz horse shoes". Then add this tag to all related hubs, create an rss feed from the url by adding ?rss at the end of the url generated from your tags and burn the feed on feedburner to help you with ping your hubs when you create a new one.
Create a blog on blogger and blog on your hub topics creating unique link backs for your hubs.
Finally, join the friendfeed service.
