Thats a pretty good explanation. I always wondered why do people love filters so much.

I think another reason is because its "cool" now.

Wow. I thought the lemonade stands was a metaphor for small startups. Not actual lemonade stands by 6 year olds.

ADW is overrated and very expensive. Specially if you need an expensive keyword. I had a good experience with Facebook ads. It was cheap and high CTR.

facebook ads don't convert into buyers - adwords ads do - that's why it cost more. if you do the proper research, set up your campaigns and ad groups correctly, add negative keywords, adwords can work really well. you need to play their quality score game, get a good CTR on your ads and always be testing new ads.
