(I think Leaf might have talked shit about my Porter at the last CBS meeting)
I think there are two reasons this might happen. The first, maybe there are not enough commercial beers around that have fruit in them and people are making homebrew to fill that void. I certainly homebrew to get weird British styes that are hard to find here (except at Goose Island, who seem to think they are a British pub dropped in a disgusting strip mall, may Nisaki bless them and deliver them from the evil of a 49% ownership stake by AnBev).
The second option is that people are trying to hide flaws with fruit. It doesn't work. I'm a novice judge and I'm always at the fruit beer table. Funny story, I didn't think to mention my nut allergy to a competition organizer one day and was almost felled by a Hazelnut Porter. It is BEER! As Laguniutas say on their excellent 13th anniversary beer, "This is a Bronze Age business..." But the fruit and strange flavors prevail. Its tricks, and you don't want to do tricks until you have the basics down. This isn't Tony Hawk, you don't pick up your board and go. You have to learn to skate, then you can try to ollie. Don't try to start with a tail-whip-slide to double-olly through time travel to smacking your own baby bottom before the doctor can at birth while you stare at your own placenta following you out. Leave that until you've mastered getting water, grain, hops and yeast together to make a decent beer. Then be great.
As BJ told me one day when we were kids: Learning to play guitar and then adding effects is heavy metal; using effect pedals to learn guitar is grunge. Who's beer are you going to drink?
Oh, and I made some rye beer one day but screwed up the yeast. Read all about that here.
