Avast Webrep rated your site with one red bar (out of three). That means something like "this site has a bad rating based on a small amount of feedback." I was paraphrasing. I just wanted to let you guys know because the red bar is kind of alarming looking. (The alternative is green bars, or maybe more red bars.) I don't even know why Avast is rating my Google search results, but that is what it said.
It probably means one or two disgruntled malcontents decided to give us the long finger salute. It happens. It means nothing with what is obviously a small sample. You can't please everyone, and you do a disservice to the many loyal members if you try. Ever notice how the most strident voices are so very fond of complaining to the world?
