That's actually quite an interesting assumption ...worthy of a "like" dare I say... but will amplify that approval with more expression of thought.

I'm often surprised when my (more often that not TOO wordy) posts are "liked" on the few forums I have frequented. The affirmation helps me know that there is at least some resonating frequency in common with others who feel the same way, even though they may not have had the time to articulate them.

I am equally edified (well, maybe more like mortified) when, after posting something I feel strongly about, and took great pains to advocate... is met with crickets.

It is interesting to discover those areas of ambivalence, as well as alignment, even if in anonymity.

As for the "dumbing down" of the internet, nothing is "dumber" than the ridicule and name calling that is so easily spewed and enabled by anonymity. I was surprised to find that in some forums on flyertalk, but even more surprised to find it on a retiree forum I frequent. Experts say we revert to children again as we age... well by gum they're right!

Any measure that is taken to reward respect, civility, and maturity in conversation makes for a more sustainable online community. I'm sure both the proponents and opponents share that goal in considering (or vetoing) some type of reward system for useful posts (aka "likes").
