and i would like to keed an eye on what you mentioned. still we have to take P/E into reckoning.
big guys have an additional advantage: they use $$$ to buy out infant competitors like utube. then noboday can compete with them. however, i am sure there is, are, and/or will be brave David(s) infront of Goliath(s), before being listed somewhere.
one more thing i think internet companies you mentioned are nolonger hitech thing liao! as no body take agri companies bio-chemi-physic-physological, even though plant photosynthesis is such a bio-chemi-physic-physiological precess. :p
