Ehowcaholic
Someone that is suffering from an addiction to the site ehow.com.  They are constantly glued to their computers, especially the ehow forums.  They are known to log in multiple times a day to see if an earnings update has occurred.  They are constantly looking for new ideas for "how to" articles.  Some even go so far as to mutter to themselves and even write ideas down in the shower.  As a side effect of their addiction to ehow.com, when earnings do not update, or they are unable to log onto the forums they become very removed and emotional as they suffer from withdraws.
When used in a conversation:
"That kid is always on the computer looking at ehow.com.  They are constantly refreshing the forums page to see if new posts appear and then checking to see if his earnings have updated.  I think they might be addicted."
"Yes, they are a real ehowcaholic!"
