Visited the site and spotted that I had a new "like" on one of my images. Which one? Went to http://www.rgbstock.com/mostlikedtoday/ and was told "no likes today... Confused! Is there some circumstance where this is valid behaviour? Is it a caching glitch?

It can take time to show up in all places.
Colin, normally it helps well to click *exactly* on that tiny blue box with the white  telling you that you have a new like. This usually directly opens the link to the freshly liked photo. ( It is as you said - your http://www.rgbstock.com/mostlikedtoday/ page. )
Unfortunately the liking system is sometimes a little bit buggy, it also counts a bit weird on some days, maybe depending on local wheather conditions ;-)
But mostly it works just fine... :-o
That's fine - I did get there via the little blue box with the white . Not really worried - just in case it was an indicator of something perhaps more serious going wrong that might not have shown elsewhere - but if the liking is known to be a bit flaky I'll happily ignore!! :-)
