Content drought....

[Squintina]

Most of what you listed is pointless content. hunt logs, sight seeing and achievements aren't really what I personally consider enjoyable content.

Achievement hunting isn't really content, considering achievements like the Gold Saucer Jumbo Cactpot one exist.

Just because it's not content that people particularly enjoy, or they find it pointless, doesn't mean it's not content. It's just content you don't enjoy (like me with pvp, I don't enjoy it, and I do find it pointless, but it's still content, just not content I'd do very often)
Is doing an achievement that requires doing instances multiple times really that different from Wondrous Tails (which generally people do consider to be content), or from doing relic quests?

You're all certainly free to find them pointless and not want to do them, but it's still a form of content.
After all, I've met some people who only do hunts because they want the mount reward. The achievement is giving them a reason to go do something in order to get a reward, it's a form of content.

The problem is the lack of more diverse forms of long term content, and that there needs to be more effort to make older content relevant.
