Yahoo. As much as I love GAG, most of the answers here are entirely fruitless. You find a lot more egoists who exaggerate their sense of importance, prioritize their ego stroke over truly helping someone out, and their whole answer tends to be very basic. I've noticed that a lot of people here seem depthless. If they're citing professional or researched information, it's solely for the purpose of trying to be a show off intellectually and some useless effort to bicker and be argumentative, not because they're actually trying to help someone.
Most of the answers I've seen and received here truly have no use. There are very few people who actually know how to give meaningful, powerful advice unlike Yahoo.
Yahoo certainly has better learning place questions and answers. I would never ask a question about something school based on here. That being said this place has better everything else so I prefer this place.
Yahoo answers may have had a higher ratio of intelligent people using it, but that's not to say that there aren't intelligent people on here too, because there are. I think most people prefer the ease of site use and layout, and the sense of community on G@G as opposed to YA.
I used to be a yahoo answers user for a long time, but ever since they changed the layout from green to purple it has just become detestable and no matter how much people complained nothing would happen. Also, it was harder to become closer to others on there I will say that people were much nicer and more helpful/intelligent on YA. Thats isn't to say there aren't some helpful intelligent users here though. I overall like this site better and won't be returning to yahoo answers.
Definitely yahoo answers. A lot of answers on this site are either biased, racist, sexist, perverted or just straight stupid. But what can I say, I still love this site a lot. I have seen a lot of intelligent answers I must admit but a lot more shitty ones.
I like gag. But the questions I answer now are few and far in between. There repetitive and quite stoopid (spelled this way on purpose lol). It's the dumbest sex stuff you can possibly come up with, ask in a million different ways.
It's not even questions that help you get inside the female mind or male mind anymore. GIRLS ASK GUYS, GUYS ASK GIRLS. It was to get some insight on maybe a gender relate md issue. Now it's just let me ask a question, just to ask -_-.
