I just don't normally tell people what to do with the game if they don't ask for suggestions. Ralph asks me every tournament what he can do to improve. On the flip side, S2 was going on for a while about how he beat me at the small tournaments, which leads me to believe that he sees himself as equal or higher skill than myself. This is fine, I don't care how people perceive me (and I actually like being underestimated), but this also means that I won't come out and tell someone what they should be doing better when they already consider themselves equal or superior to me. I help people who want help, and the less you think you know about the game, the better you will become.
Here's a fun tidbit, did any one here know that pretty much all of my Marth success has come from talking to CJ? CJ isn't very well known, and doesn't place high, but that guy knows as much about Marth as Judo knows about Shiek. Whenever I have a trouble match up, or need advice, or need him to go back to 2008 and start the metagame over for Marth again in writing so I have a chance to catch up to today's Marth metagame, CJ does and it has helped me immensely.
The more open you are to learning, the more likely you are to learn. Everyone can teach you something or give you ideas. Truth be told, I like going to anime con tournaments just to watch how people play when they aren't involved with the community. Some times I get great mind game ideas just from watching people play unorthodox.
So eat your vegetables.
