There are some guys in the HOF that lowered the bar, but Biggio isn't going to be one of them. You don't seem to be considering the position he played. Second base is one of the most difficult positions. Catcher and short are generally considered the most difficult, with 2B slightly behind, and all other positions substantially easier. Gary Carter (a catcher for those too young to remember him) was a .262 hitter, and a very deserving inductee.
Because of what he did while also playing gold glove second base, I would argue that what Biggio raised the bar substantially.
You and Tom offer some good points, but not enough to sway my opinion that for a 3000 hit guys, he's the most undeserving of the bunch. Baseball thinks it must add someone to the Hall each year. All I see it some cases, is a bit PR boost to get people to visit the Hall of Fame. Baseball fans will visit even without any added hype.
