nice idea suleika, i like the idea of creating a custom google software search thing which excludes bad sites.
let me say i don't fully understand the objection to software listing sites taking info from public web pages describing the software. to me this isn't really something i expect to be asked for permission about.
however for me this feature is key:
sometimes no links to the software home pages
this is completely unacceptable to me. any software listing site that doesn't have a prominent link to the original web page of the program is not one to be trusted.
