In my own perspective to this question,I think the greatest thing about Ask.com is having a good opportunity to meet new people from all ages on here which you can learn new things which you never knew before and some are surprising indeed.Being able to talk to others,have your questions answered by brilliant people and all these wonderful people on Ask.com as a community. ^_^
But also, I love how helping others enriches me. I have spent A LOT of time researching my answers, not just online. I have "interviewed" family and friends, grabbed books, looked up definitions..... Topics I would not have otherwise considered have opened up so much new knowledge. Proof positive - you can teach an old dog new tricks. And, that old dog will feel like a young pup and be grateful for the experience.
Also, this wonderful diverse community brings so many perspectives to subjects. It has truly opened my eyes and my heart.
