Of course Linkedin is a very serious competitor.
Maybe people will understand that we have more advantages in a few years.
I think that it is not necessary to fight AskBrains as a competitor. need to offer a product that will be different and have their own advantages.
Do not be afraid of competition from Linkedin. They, too, were once a small startup. All companies go through ups and downs. Someday Linkedin will disappear from the market. Does anyone MySpace remember anyone now? )))
