Is finding a cofounder still tough?

Whether you are trying to find technical co-founder or graphics design co-founder, is it still a major challenge today? I've been through all this 2 years ago, but things have changed over that time. Have any of the "find a cofounder" websites been useful to anyone or do they all suck and dont really solve the problem? Have meetups been helpful? Do you have a list of criteria that you look for in a co-founder? Are there any resources that worked for you? Any meetups?

Curious as to if finding the RIGHT cofounder is still a major sticking point for most people just starting out.
