I love my Subaru, but I'm not sure if I'm a "fanboi"...
I used to hate them with a passion. They got REAL popular in the automotive enthusiast scene in my area especially around 2007. At that time, most of the "owners" were clueless high school and college age kids whose Mom's and Dad's had bought the car for them. Around the same time, a speed shop opened locally that hired a tuner who was very knowledgeable on the cars. They eventually carved out a niche as the go to place for Subaru mods/repairs. These kids piled in the place in droves, with Mommy and Daddy footing the bill for expensive upgrades and/or repairs.
This common theme of owners is still prevalent today, although the stance movement is starting to kick in... lovely... Apparently one of the kids was unhappy that his '08 STi was slower than the more powerful '09 and up modes, so he purposely drained his oil and popped his motor so that his Dad could buy him a $9k "Cosworth" motor or something like that.
The reason I bought one was because I was looking for a fun and quick but more functional DD to replace my Ion Redline. Still harboring my dislike of Subaru's and also not being a big fan of VW, I narrowed my selection down to an 08.5-09 Mazdaspeed 3, HHR SS and Caliber SRT4. I know I'm going to need my flame suit for this one, but I liked the SRT and SS way more than the MS3. The problem I had was the price. Even used, I couldn't find any that weren't priced in the high teens. My G/F was also looking for car at the same time and had some hard on for Subaru's because she knew some rich kid in high school that had an STi.. blah blah. Naturally, she wanted to look into WRX's which meant I had to test drive a couple. Can't lie, I enjoyed them. The interior was a VAST step up from my Ion Redline, and the cars just felt better. I eventually added the wagon version to my list and found a couple locally.
I almost bought a 2006 World Rallye blue wagon, but it was having issues with the air injection pump crap, which caused it to throw a code, which disables the cruise control. I looked into the issue and found that there was really no way to fix it without shelling out $600-$1000. Eventually, I found a 2002 wagon with high miles at a Ford dealer. It was bone stock and had one owner. For some reason after I drove it, I HAD to have it. It had been sitting on the dealers lot for a while, and they offered to sell it to me for less than I was planning to lowball... I ended up paying around 1/3rd what I would've had to pay for the other 3.
As far as the forums go, I tend to stay away. I'll search google when I have a question or issue and will usually end up on one and sift through crap to eventually find my answer. Seems like most trash on people for buying cheaper mods, even if they work for their intended purpose. That's a huge clash for me, since I'm a giant cheapskate... Plus, I know that they aren't the greatest AWD 4cyl turbo cars in the world. I've had 2 AWD DSM's for the past ten years, and I know that is certainly Mitsubishi's territory... I have a local buddy who doesn't fit the usual Subaru owner mold that can usually point me in the right direction.
Subaru fanboi's definitely aren't the worst though.... Try going on forums that deal with the GM LSJ crowd (Cobalt SS S/C and Ion Redline owners)... Most of them have no idea how to turn a wrench and just blab all day about "Stage Kits" and such. I almost scared off of buying my Ion Redline, when some people on the forums told me that they remove the supercharger to change their oil.... They are even worse in person. 99% of the LSJ cars that kids drive around here have nasty looking wheels, tasteless cosmetic mods and stickers. As far as performance most only have a CAI and Catback, but still try to street race anything that has wheels. The kids inside the cars are usually wearing flat brimmed hats and big princess cut diamond earings. I used to have fun dusting them in my mildly modded Redline. After the race, you'd talk to the kids and they'd have some big HP goals, or start blabbing about the $2200 TVS blower upgrade, even though they have no idea what it entails...
