Amy is part of Doctor Who and in this story House was having mindgames played on her...of course people on the thread are going to mention her.
The entire show ISN'T focused on her. The entire show is focused on the Doctor, Amy, and Rory. It is focussed on TeamTARDIS and the secrets they hold from each other and how they'll come together and connect with the Doctor's death on the beach in Utah. THAT is what all the focus is on and that is what all the discussions I've seen have been about talking about the three of them.
YOU can reasonably believe. The TARDIS barely acknowledged Amy in this story. The Doctor's been checking out HIS pregnancy scan of her on the TARDIS scanner. And of course Amy is important because she is the third section of the bigger storyline in which the Doctor and Rory are just as equally involved with too.
Next time choose your words more carefully. And anyway - the WHOLE of any TV show is made up of the writers, the makers, the broadcasters, and we the viewers. The people who visit the Doctor Who threads ARE part of the show. We watch the show and we talk about the people involved in Doctor Who and Amy is part of that. What do you want us to do? Ignore her? If people want to talk and speculate about Amy and her part in Steven Moffat's grand-plan then by Gallifrey we will.
