well, Laura, suffice it to say, there are a lot of system issues/glitches these days!
I am surprised because this isn't a fledgling company. An issue here and there is one thing as a site grows......but constant site problems are, imo, a concern.
Why they need "Thanks", along with the Thumbs up/Down icon (that both generate the same result) is anyone's guess.
And, to make it more confusing for those new to the site - both options translate into a "Vote".
Nothing is coordinated..........no explanation for the new " thanks" = thumbs up = vote.
Either (imo) there is some big picture out there in Trulia-land that we are not yet "getting", or someone is alseep at the wheel.
