it is really tought to say what is worth keeping... a pretty good rule of thumb is if they are paything for themselves then keep them... if they are not then drop them... but it also depends on how you are going about promoting them... and what type of
SEO you have .... just to be starting off and be making 1-3 dollars a day... or 365-1095 a year is pretty good... find out what you are doing to the domains that are making money and try to do the same for the others.. just dont get caught clicking your own names you will lose everything you have earned... also try to research adsense and other paying programs.. to see which would be best paying... read the forums and save yourself some hard work as most of these people have already been there and done that and can offer you alot of advice
