I really think it matters with the quality and content of the hub. Other factors include the title, usage of keywords, backlinking, and writing about something that strongly appeals to any audience.
I personally have not writte a lot of hubs, but my hubs are doing fairly well, with traffic from the U.S. and abroad. The traffic goes up and down, but that's acceptable, because others, and not only in the hub community may write about the same subject as you.
Before considering your hub(s) as rubbish you may want to review your hubs and edit them to correct any errors, (grammar and punctuation) and add things that may be more appealing to the reader.
