Follow or like 'word war', who wins the game?

While talking to one of my friends last week, this line that lingered in my mind for several minutes, "twitter looks and feels professional". When I pushed her to explain a little more about this thought she adds, "If people in twitter can express there thoughts in 140 characters, why to waste time with a round about, unprofessional format". Starting an argument with her, I said "Twitter is no fun, even though there is still a room for conversation, which is the primary ability of social networking, it lacks several aspects that Facebook scores on". She adds on "I get more professional contacts via twitter, when I want to lack in any personal sort of communication and people have got no time to read an entire essay from me". 

Venting into a debate, I said, "Facebook allows me to get to know about a person more quickly than what twitter does, it even acts as a ice-breaker at times".To add a bit of background to this argument, a person whom I know personally has about 18k follower and has no room for conversation on the twitter page. And the possible reply that I received, "Its not feasible to felicitate an argument or a conversation when your follower list exceeds a certain limit, no more it becomes a private conversation, it extends into a public debate". This reply seems legit, but breaks the point of social networking.

Facebook and its new hashtag got no meaning

A Facebook page this is not twitter. Hashtags don't work here says, "I don't mind seeing TOPICAL hashtags on Facebook. It's been pretty cool to see a variety of opinions on the political events that have happened in the US over the past few days".
