Well the way I saw it--
"You're early!" said Hermione, moving along to give him room to sit down. "I thought you were with Cho, I wasn't expecting you for another hour at least!"
Hermione's just as excited as she gets when she sees Harry after his stays with the Dursleys... Why? She knew he was coming, she saw him a few hours ago and told him to come-- so it's not like she's really that surprised. Because she doesn't like Rita or Luna??-- well she doesn't like Snape or Umbridge, but she doesn't run up to Harry with exclamation mark salutations after one of their classes does she? She's happy because Cho isn't there. Simple as that. She's so happy Cho isn't with Harry that she doesn't have time to contain herself.
"Cho?" said Rita at once, twisting around in her seat to stare avidly at Harry. "A girl?" She snatched up her crocodile-skin handbag and groped within it.
"It's none of your business if Harry's been with a hundred girls," Hermione told Rita cooly. "So you can put that away right now."....
Why so irritated? She doesn't like Rita writing articles but...
...
"Pretty girl is she Harry?"
"One more word about Harry's love life and the deal's off and that's a promise," said Hermione irritably.
"What deal?" said rita, wiping her mouth on the back of her hand. "You haven't mentioned a deal yet, Miss Prissy, you just told me to turn up. Oh, one these days..." She took a deep shuddering breath.
"Yes one of these days you'll write more horrible stories about Harry and me," said Hermione indifferently. "Find someone who cares why don't you?"
Now here's the catch, after two angry retalations with Rita mentioning Harry's love life in a way not related to her why become less offended when Rita directly relates her web of "fiction" to HER and harry, shouldn't she be more angry? It's like when a rumor about someone else starts and you feel bad for whoever it's about, but when it's about you, the reaction intensfies to why, the hell is anyone making something up about me? And then there are those rumors well that people like to keep, because something in them they like... she doesn't care, she isn't violently against Rita mentioning them together like she was with the mention of Cho/Harry because she wants it. Even if she hasn't admitted it to herself yet. Look how angry she is at Rita before, it's not so much because of Rita's stories but the implications she's talking about. Once HHR is implied Hermione has NO problem.
By the way thought this was a good side note:
"The Phropet wouldn't print it. In case you haven't noticed, nobody believes his ######-and-bull story. Everyone thinks he's delusional. Now if you let me write the story from that angle--
(567 US Edition)
Everyone thought Harry was delusional, and guess what--they were wrong!

Isn't the phropet the name of the paper Leaky is running up to the release of DH--why won't they print our views? Because everyone thinks we're delusional.
I was just reading about one of us going "under cover" as a heron and acting like she/he was worriedly wondering if R/Hr was the red herring. Surprising but some herons were civil and replied that none of the major ships were really destroyed in book 6, and familarly enough they'd still have fan fiction if that ever happened. It's all about angles, and approaches, JKR could've been pacing the IOD at an angle, writing HBP at an angle, everything to throw us off the trail until low and behold all the "dinky-little" HHR sites turn out to be as dinky-little as the Quibbler after Harry's story was published.
