Best alternatives:

• go out and walk and talk to 5-10 people (5-7 may ignore you, fine)
• the 2-3 that respond genuinely, it gold
• use Couchsurfing, join their events it's not just place to stay
• use Hangout in Couchsurfing, it will scan the nearest location to see who is active and you can send a quick message to hangout, they have option to accept or not
• likewise, you can create a Hangout and wait for others to join
