I don't think so. Maybe last year but now it is so hard to get income from bounties and airdrop. A friend who suggest this site to me never log in anymore since August. I'm still trying to get my first reward from bounty and I don't know when, maybe next year or never.
Its going to be harder for new comers who only wants bounties here in the forum because its going to be a lot of work this time. Not to mention the merits they have to collect before they rank up. Twitter and facebook is the very option of those newbies. Article writing is also a good one but for someone who is new, they better have previous profile where you have good number of followers and readers as some campaign requires this much.
