I don't want to specifically say this site is good or bad, but I've had really bad experiences with sites of this sort.<p>Essentially, sites of this sort were all just recruiters trying to farm up candidate contacts, and all you are left with is just spam.<p>My advice to underdog.io: tell us who you actually are. What's your name? What experiences do you have? Your "About Us" says nothing about you, and makes me suspicious that you don't want to put yourself out there.
