i propose the theory that the mentions on the captain's blog are less pandering and more of an attempt to clarify the relationship between jack and ianto is based on more than sex. why bother? because the captain's blog is generally used to clear up the relationships on the show. look at how he talks about the other characters in the blog. i think it's a general clarification process because the relationships are dealt with in subtext.

I find that slightly problematic, though, the fact that it is felt the relationships need clarification tells me that they're aware the onscreen clarity is lacking. [devil's advocate]I think it's interesting that they feel the need especially to clarify it for an American audience, there's been nothing even vaguely similar on the British site. Do they think Americans are just slightly less sophisticated and need stuff spelled out to them that little bit more?[/devil's advocate]
