i definitely do not think that reviews have to be as long as some of the ones i have done; god help us if they did.
but, i am a little concerned that whois tools might not be "meaty" enough for a full review.
also, if you are only looking at freeware tools, that might be a bit of a problem for a full review since our reviews are supposed to encompass all programs, including but not exclusively freeware.
i think a related subject that would be worthy of a full review would be network information suites, that inlcude whois, ping, traceroute, etc.
but thats a pretty involved review and i'm not sure you really want to get into all that.
we definitely want to draw a distinction between our full main reviews, which give out awards and are expected to be long(ish), and have a somewhat consistent style and approach, and mini member reviews, which can be whatever our members want them to be; so my comments are just about trying to strike the right balance there.
