ID # in URL not good for SEO?

Using ID# in URL

[Brindara]

I remember reading somewhere that it is not a good for SEO to use ID # in URLs. Does anyone remember what was said about this and why?
Thanks.

I've been aching for a long time to mention somewhere official that sites shouldn't use "&id=" as a parameter if they want maximal Googlebot crawlage, for example. So many sites use "&id=" with session IDs that Googlebot usually avoids urls with that parameter...
