facebook has been profitable every quarter making millions. twitter has yet to actually make any money, yet there stock price is stronger due to popular demand. it doesn't make sense. the market rarely does. facebook seems to be far better investment due to there profit from main site and growth from there secondary instagram. but twitter does have more users and is growing. it just isn't making the money it should.....this is a weird question. but hope that helps.

I don't believe facebook to be a bubble, its stable with strong income, it has other sections of business that are growing as well. they done what no one else has by monetizing mobile views, making them innovators and more profitable. linkdin is a solid company, but they don't have nearly the users of facebook (not counting the fastest growing social media site instagram under them) but they are making money. I feel decent about reasonable investments in either. but not twitter. twitter does have near the income nor the ability to add to add to it, they do have a lot of users if they can ever make money off that (advertising) they might be a decent investment, but right now id stay away from them.

I was born, that was good.

life is only two days? that's not very long.

they all mean "the" but refer to the gender of the item, the man is "der mann" the lady is "die frau" neuter is das, "das hotel", masculine "der" feminine "die" and neuter is "das"

sharp really comes from the other definition of sharp, like something that cuts easily. a shape blade, thus someone has a "sharp" or quick brain. keenness or keen has two definitions that I know of and people use (southern americans) sometimes people are keen on someone (to be attracted romantically) such as "now boy, you aint keen on her are ya?"(ya being you, aint being are not combined) keenness I have also heard being used as to be aware of something, but im not sure that is the correct usage. I hope this helps. the main thing is to keep in mind that keen is rarely if ever used. sharp is fairly used as to have a quick wit or to be mentally quick. good question hope this helps.

someone could say ill give you a lesson, or ill teach you.....but if someone you have a problem with ever says "im gonna teach you a lesson" I suggest you stay away from them.

I assume regular American food, only thing particular that comes to mind is syrup, that's popular there, famous for there syrup they make.
