Initially neither Weekly nor Nightfall had match-making. Public outcry eventually made them change on the Weekly, but they're still holding to their decision on Nightfall.

I would suggest you find a group to hang out with, so you know they're good. Sites like http://www.destinylfg.com/ and http://the100.io/ will connect you with other people wanting to do the same activity. Some of the groups on the100 also have clans, so you can join there and not play with strangers.
