Something to consider, those of us with lots of snakes may do things in ways that aren't really practical for the average person with one snake, such as housing. I keep my snakes in racks, but someone with one or two snakes may keep theirs in a tank.
If you are going to judge someones advice based on how many snakes they keep, I think a better way is to do it based on how long they have been keeping snakes. I have 23 ball pythons, but I've only been keeping snakes for a little over a year. There are plenty of people with just 1 or 2 snakes that have had them for much longer.
That just my.
