Agreed. The Like, Link, Flag, Bookmark etc. icons are all but invisible... I actually spent a good 15 minutes trying to figure out how to like a post searching the FAQ and Forums until I just happened to see it. Even though I know where it is I still have a very hard time pressing it as I have to take a good close look to make sure I don't hit 'Report' instead (which has happened many times).
Please fix this ASAP... We know you have plenty of other things to worry about and this may seem a small detail but it is very important to us.
There also seems to be an issue with the background images in our profiles but that's a post for another day
