I like Teyla/Ronon too! Of course, I also like Ronon/Elizabeth so maybe I just want to find him a good woman.

I think sometimes I'll watch the show and be all "Oooh the John/Teyla's will be happy tonight" and so when it gets mentioned I feel all smug about my opinion being confirmed. Maybe it's also because it could possibly become canon that people are more on the lookout for it. Of course, John/Rodney is already canon, so there you go.
