This is a consensus for the implementation of a weekly series of blogs which talk about changes in the wiki, updates to TESO or any other game related to TES, as well as maybe a community poll, consensuses which haven't met a conclusion, and interesting new lore theories.
The purpose of this is to create something which people can check out every week, and it may even get more users involved in the wiki, if they enjoy the blogs. This isn't something which should be taken entirely seriously, this is something more upbeat and leisurely to get people involved in the wiki, in a way where they don't need to read two thousand policies on how to write about Ulfric's voice.
This is also a good way to make sure everyone on the wiki knows what's going on, so if a brand new lore theory is taking the TES world by storm, the blog will keep people up to date on what this new theory is. This will give the News Team something to do, and may spark interest in others who wish to join the News Team, so our community may grow.
A couple examples of similar things on other wikis:
This sounds like a good idea to attract contributors to the wiki through blogs and help bring life to the community.
As for lore, I think there should be precautions about discussing it, as I have seen many haters of Michael Kirkbride as well, even when the latter's work is still being used in the Elder Scrolls series in more ways than one.
1) Lack of regular, relevant content for a weekly series. Going by your suggestions:
Talk about changes in the wiki: Sometimes weeks go by when there aren't any notable changes on the wiki (such as policy, etc)
Updates to TESO or any other game related to TES: Looking at general ESO activity over the last few months, updates are not weekly, TES news is slow and older TES games are not being supported any more.
A community poll: This could be something more regular, provided it's something interesting and will generate discussion.
Consensuses which haven't met a conclusion: General updates on CTs would probably fall under your first point, but again it depends on if there is anything to report on a weekly basis.
Interesting new lore theories: Many new theories or discussions take place every day on large lore communities, such as the Bethesda official forums or reddit. Our lore forum is fairly dead and contains very few theories, so it would mean directing people to other forums for them to understand what we are referring to. Another problem here is who decides what ones are interesting and should be included in this update?
2) Reliability of editors. Who will participate in this? Who would be responsible for ensuring there is a regular blog post? Our news team? If this would be a regular main page feature, it would need to be of high quality - can this be ensured?
Looking at your example, the Fallout blog is really just a poll and nothing else, but the author makes it interesting and funny, which is what we would need.
Like I said, I generally like the idea and I know its just for fun, but weekly is probably too frequent. Bi-weekly or monthly might be closer, depending on relevant content (and not filler). It just really needs fleshed out more.
While it might be hard finding significant relevant content every week, I believe that there is usually enough to keep it interesting at the very least. As for the reliability of the editors, I believe that at this stage the community has come to recognize the most active/notable members of the community. But it may also be a good chance for lesser known contributors to start developing a reputation of their own.
Biweekly sounds good, and it doesn't need to be a strict schedule, if one has come out the previous week, but there is something new this week, then there can be another one. My one problem with it being monthly is that the idea of these blogs, are that they are frequent.
When it comes to reliability of editors, the current News Team would work on it, and since they were put in to the position of being members of the News Team in the first place, they should be able to deliver high quality blogs at a frequent rate. I can join the News Team as well, to help out with the creation of it.
Edit: In response to the point of who are the ones deciding whether something is interesting or not, I think the News Team should being able to judge whether or not something would draw people's attention. And on the lack of frequency of news about TES, it's true that news on the TES games themselves are slow, but just by scouring the Bethblog, news can be dug up, like Skyrim being on a sale on Xbox Live or something.
