Oh, I don't know; Sometimes you get some interesting stuff that's not strictly MediaWiki / Wikipedia / Wikimedia - related.
I consider this primarily a strategic tool to improve communication about what we are doing.
Wow, that sounds really quite dull. I read the words "strategic", "communication", and "tool" all in the same sentence, and I started to lose consciousness and the will to live :-(
This stuff is supposed to be fun, and if it's constrained too much, it ceases to be fun.
Besides, what does Wikimedia communication mean exactly? Does it include people developing extensions that aren't (at least at first) going to run on the cluster? (I'm assuming not, since that's not Wikimedia-related). What about Wikia stuff? (I'm assuming that's out too, since it's not Wikimedia-related). What about volunteer developers thinking about ideas? (I'm assuming that's out too, since there's not much related to the WMF per-se in what a volunteer dev does with their time). What about the citizendium folks? (Certainly not Wikimedia-related, although their endeavours at the very least have the potential to be interesting). It doesn't leave much, and what it does leave isn't likely to be very interesting, especially if people self-censor to fulfil some strategic business communication objective.
In short, I can sort of understand why the WMF might want to _write_ something like this; I'm just a lot less clear on why normal people would want to _read_ it.
Wikimedia is not a generic blog host.
Agreed: The WMF _is_ constrained in this way, but _I_ am certainly not. Furthermore I think my conception of what a planet should be (anything goes, just try and make it fun, and interesting, and semi-wiki-related if possible), and your strategic-communication-objective have irreconcilable differences.
So I sincerely wish you good luck with what you're trying to do; run with it, and I hope it works out well.
But me, I'm setting up a very simple planet as an experiment, that pulls in a diversity of wiki-related-blogs, but which is not restricted based on the whether or not the content is official communication approved by the WMF; In short, I'm aiming for the kind of wiki-related planet that I would actually like to sometimes read. The occasional evil cat doing tricks in New Jersey restaurants is welcome, provided the author has a major interest (social, technical, administrative, etc) in wiki-related things, especially the Wikipedia, the MediaWiki core, MediaWiki extensions, and also Wikimedia, but other wiki-related stuff (e.g. wikia, citizendium, Wikipedia on the OLPC, etc etc) is all good too (provided it doesn't drown out other stuff).
An initial version is already up and running at http://WikiBlogPlanet.com/ ; (If that URL doesn't work for you, leave it 24 hours for the DNS to propagate, & then try again). To start with, it's based on Angela's blog list ( http://wikiangela.com/wiki/Blogs ), including everything in the "Wikipedia/Wikimedia/MediaWiki" category, everything in the "Wiktionary" category, everything in the "Wikia" category, and a handful of things from the "Miscellaneous" category. Anything that I couldn't get a feed in English for was omitted. Also there are tend to be a _lot_ more blogs about the social aspects of wikis, and far fewer about the technical aspects, so the I've tried to include all the technical ones, but haven't included all the social ones from the "Miscellaneous" category, to try and get some semblance of balance between technical and social. Currently it's set to automatically update once an hour, so there may be up to 60 minutes delay between when blog entries are posted, and when they appear on the planet.
Also if you want to be added (especially if you have or start a technical blog, as that's the most underrepresented category) either add yourself to Angela's list or email me directly (or preferably do both). Also if you don't want to be included, please let me know and I'll remove you. And lastly, the Planet software has a concept of a "Hackergotchi" ( http://en.wikipedia.org/wiki/Hackergotchi ) - the planet software seems by default to want a PNG image, 65 pixels in width & 85 pixels in height, so if anyone wants to have a little image of themselves against their blog postings then please either email me a suitably-sized image, or send me a web link to one.
All the best, Nick.
