I feel the same way Hellpuppy and rarely show anyone any of my sites anymore.
I used to show my sites to those that signed up under me to promote ClickCash to give them ideas and got tired of all the 'similar' sites that kept popping up. The final straw was when one day this guy ICQ'd me all proud of his new site and told me he'd worked very hard on it and sent me the link. It was a direct copy of my entire site except for a few small graphics he'd changed and a word here and there. He actually did not think he was 'copying' but only 'borrowing'.
