Hi Halfdeck, long time no see, hope things are good
I can't agree with you on 'But the surfer expected the thumb to go to a picture, not a tour' in the sense that it's the same as the text being blind - if a surfer clicked on a text link that said 'her first lesbian sex' he'd expect to go where he can see first lesbian sex, and that's exactly where he'd end up.
I also agree with msanchez - too easy to remind the surfer to type in, or if no spaces are used, to simply copy & paste with the .com attached.
