Let's be honest: all new platforms and technologies are first used by geeks. Everything will sound geeky for a certain amount of time. Go back to 1980 and ask someone to "Google" you. Let me know how that goes for you.
Also, I believe the past tense of +1 is +1'd, not "plussed".
Yes. Yes, it is.
Not that I think that's Google's problem here, but yeah, "like" is much more natural than "plussed".
Including social networks? I highly doubt that.
> Also, I believe the past tense of +1 is +1'd
Which just proves my point, because "I plus oned that" is even more difficult to say and type. The word 'one' has no fluid way of being written or spoken as a verb. Plus one'd? +1-ed? Plus 1'd?
And yes, telling someone to 'like' something is far less awkard. Like is already a verb.
