Perhaps allowing sigs might restore that sense of community
I say nay in that regard. And I also say the sense of community is strong. What we are seeing is weariness as the glut of noobies continues like a rising wave, and dang few of them are smart enough to read the road signs, or even the archives.
At some point even the most dedicated just turn a blind eye to the next query that makes no effort to research the wealth.
There's only so much free that can be given away to those who lack the desire to research first, begging for shortcuts...
So, yes, there has been a backing off... then again, there's dang good reason to do so. As a rule we don't solve newbie questions, we guide them to learning how to solve their problems. And... that's the way it should be.
And WW is not going away. There's nothing like it on the web.
Just my 2 cents (1966 valuation).
