My science fiction prediction is that the aliens rank all species and then avoid them if they don't meet certain standards.

One of the rankings is probably: # of web sites that fail to specify image sizes statically so that the web page ends up resizing itself while loading vs. the # of sites that are nicely done so things are moving out from under me while I'm trying to actually read or use the bloody web page.

You can guess where I think humanity lies on that scale.
