Some things I'd suggest:
Kill the OOC channel. It destroys all sense of immersion and makes IC interaction pretty difficult for some of us (Or, more likely, just me). Sure, sometimes we need to explicitly state stuff in OOC during meetings to get the point across, but that's what raid chat is for. Stupid things have been happening where multiple conversations are going on at once, random comments made that detract from main subject or planned agenda, people on the other side of the world adding their opinion on a subject we finished covering hours ago, some trying to connect their Skype accounts while the others have to wait... etc an' all that.
We didn't use one at all in the old Herald, except for a very brief trial run during which it proved very unpopular, and we still got the job done perfectly fine.
Random Rambling. No planning needed, just gather somewhere and go walking for an hour or so. Just chat and explore, embrace whatever random rp you come across and see where it leads. Even if you don't find anything you're still getting seen in public. If someone's advertising a shop or service in a channel, divert your route so it goes their way and check it out.
Tutoring. Take the cub reporters on a field trip to learn the art of a particular aspect of reporting. Things like Interview technique, note taking, story fishing. Take them to meet the more active names in the community (not just the famous ones). Even if there isn't a story about them, the recruit'll be learning useful skills and start networking, all while being IC. Take the veterans out on trips like these if they need a refresher.
Attend events as a group. People love seeing a Herald reporter show up to their event, how pleased would they be to see two or three, maybe more? Also attend the smaller shows you think might not be that good or a front pager. It may not be the next major war, but that pet show is quite interesting to some of our audience, and is good practice for the less experienced reporters to try at. There's more going on in WoW than war and politics!
Feedback/Opinion/Review meetings. Get opinions from the readers after each issue and find out what they thought of it! Do this by directly approaching randomers and organising public meetings for anyone to attend and have a say. Did they find an article too long to hold their interest? Was not enough evidence given to support the writer's arguments? Is too much emphasis being put on Stormwind? Gather the data then have a private meeting between ourselves to discuss the stuff that's constructive. It could be good for your technique and perhaps help us identify what makes an 'excellent' issue over a 'good' issue.
Public debates. Take a major article from each issue and have a heated discussion with the public. Invite guests who have particular knowledge or experience of the subject. Get opinions and use them for a "People's Voice" article in the next issue as a follow up. Perhaps do something similar to the BBC's Question Time? (Panel of guests, an audience with questions. Cue debate!)
In-Herald Kudos awards. Have regular meetings just for rewarding members for their achievements and contributions. Maybe someone's provided the front page article for three issues in a row? Perhaps they took extreme measures to get that awesome scoop? Make them feel good about contributing, and make sure the others see that it's a good thing to strive for. Maybe they'll up their own effort to achieve better as well? The whole point of the event is to reward longer serving members and encourage the new ones to do the same. A big back-patting session, basically.
An annual public award ceremony Kind of like the oscars (maybe a 'Henry' for the Herald?), but for our server's community. Have readers nominate those they think should be rewarded for their effort and have a public event that celebrates the winners. Things like "Best Military Commander", "Most Charitable", "Most Devoted to Their Cause", "Biggest Douche in the Galaxy". Sure it's an evening of big egos, but could be fun to try and could give a lot to write about during the run-up and afterwards (the nominations, the fashion, the reactions, the speeches, the controversy...). We could do OOC awards as well, but keep them in the forums and website.
Link each article to a feedback thread. Put a very visible link at the beginning/end of each article in an issue that links to forum thread made for comments on that specific article or issue. Get people to discuss it there and join in with them (i.e. Always reply to the comment, don't leave it to sit on its lonesome and let people think we ignore it). If people don't post anything, start the chatter with your own opinion!
Guest writers. Invite specific people to write one-off articles on a subject of their choosing (and related to current affairs).
