Why so many anonymous / guests?

[robsryder]

I am curious as to why this website seems to have so many more "guests" or anonymous users than registered members. For example, at this time as seen from the Main Forum page there are 496 guests and 91 members shown - a 5 to 1 ratio. That seems a bit much for something that is a member benefit (this website).

It seems easy enough for MOA members to register and login. The resources used for recruitment of new non-members (i.e., guests) should be separate from the members' website / area. Am I misinterpreting the guest / member data?

I also see that we have a number of "spiders" from the various search firms (e.g. Google, Yahoo, MSN, etc.). Why are these entities permitted to be present and what advantage to they offer the MOA?
