They make great pets. Spiders in general do. You'll have the odd one who thinks it can take you, despite you being an enormous mountain compared to it, but in general they very quickly tame to being hand fed. They're smarter than one might think. Some are stupid though. 
 
I've rehabilitated wolf spiders before, i.e. looked after them and hand fed them until their legs grow back or whatever the issue is. They're very tidy and will collect the husks of their prey into a cute little graveyard to keep their cage clean. I've not been bitten by a pet spider yet. All of them were from the wild, not cage bred, though I did breed some for a while. Had issues with the mothers carrying an egg eating parasite, it was endemic and epidemic in that place, likely caused extinctions.
 
We used to get bitten doing cropwork though. There were pale whitetails by the millions in this one orchard, an each spider owned one orange it thought was its private planet. If you picked it, you'd get bitten. So we got bitten hundreds of times each day. We got so used to it so quickly we stopped reacting altogether and now I'd guess we're probably sensitized to their venom. They reckon you can fail to react thousands of times but your body is slowly and permanently losing its ability to cope with each bite. 
 
But they're such beautiful little killing machines. Fascinating predators, jumping spiders might be my all time favorite.
