Personally, I really enjoy the Wiki newspapers people run. I don't know why they've gone so out of fashion.
Well, if anyone cares, I have quite a lot of experience running wiki-papers for the game. I ran The Rampant Lion for Perdan, which developed the format that most newspapers changed over to for quite some time. I ran the TattleMaster, an OOC-based paper about the game itself, including various changes, bugs, bugfixes, etc. And I ran the Dwilight Daily for a few years. It was fun for quite a while. As for why they all burned out, well, I can speculate based on my own experiences.
1) It gets repetitive. There are only so many things you can write about, and only so many ways to keep telling the same story over and over.
2) You get very little feedback. Almost no one ever comments about it. Is anyone reading it? Does anyone care? The people in your realm probably won't. Most attempts to get the realm involved are met with silence.
3) You get
zero help. Or so close to zero as doesn't matter. You may occasionally get someone to help contribute. But beyond that, it's a really lonely undertaking. I had the best success with the Dwilight Daily in getting more people involved. Eventually, though, they trickle away, and you're left doing it yourself.
4) It's all propaganda, and everyone knows it. Chances are that everyone already knows all about what you're going to write about. You're not writing anything new or surprising. And if you are, then chances are that it's secret information that people don't want you telling. And if you do tell, then they will stop telling you in the first place.
5) It feels 'weird', I guess, writing a modern-style newspaper for a medieval environment. Newstickers, interviews, headlines, etc. It doesn't feel right.
Anyway, those are my views, based on my few years running various wiki-based papers.
