You are faving correctly as I can see the ones you are faving on your profie. You can either fave from the DB a I suspect you are doing. Or if you pull up an LOL from somewhere else, when it comes up, in the upper right side is a yellow star and when you click on that, it "faves" the LOL to your "Favorites". You can also choose to vote for it under the LOL. If you have My Sites, you can also choose to fave it to a site you have created at the same time.
Not sure what you are asking. You do know where the Front Pages are posted right? People like me who visit the front pages then can see the few the ICHC moderators have picked to be featured. As far as "crossover" - LOLs are posted on the various sites such as cats, dogs, animals. Then some who do well on the sub sites are picked to be reposted on the I Can Has Cheezburger which is the "parent" site of the sub sites. Does that help?
Yow! Sounds scary up there...today more spring weather here. Actually we have been seeing mountain animals in my neighborhood, but later in the year. Bears in the summer particularly. Several mountain lions last year...the poor things are starving when it's too dry.
