I think the main flaw of micro/macro blogging in form of social networking site is, sometimes you write something wanting to inspire people, but in the process you end up trying to impress people instead.

It's not wrong, but sometimes you can tell when someone has a genuine intention but just overdo it. All of us would surely fancy some likes (and retweets, in case of microblogging), but by no means we should scream for it. Be yourself, don't run around looking for the spotlight, the cream always rises to the top anyway.
