What do people want to read about?
I'd suggest two broad themes, the state of the game and game-related fiction.
State of the game
Match reports - Cogs, events, informal leagues, challenge matches (clan vs. clan, clan vs Muse), duels
Patch notes - bare facts, opinion on direction the game is taking, anticipated effects on established builds
Screenshots - arty, illustrative
Strategy and tactics - ship builds dissected, team builds, map discussion (eastern vs. western routes on Canyon, going over the mountains on Fjords), tutorials (counter-sniping, dealing with fire damage)
Duels - issued and accepted, "Lord Dick Tim, your mother was a hamster and your father smelt of elderberries, I challenge you to a duel in Canyons!"
Game-related fiction
Game lore expanded
Fan fiction submissions
Clan fiction
The state of the game stuff is what interests me, but getting regular metagame onservations and collating them could be a chore after a while. If Muse could be persuaded to provide (non-commercial) game stats could be useful and interesting - ship usage, weapon usage, ammunition usage - if these are collated. 30% of players choose Goldfish, 12% of players choose Spire; global hit percentage on all guns is 30%; 42% of all match outcomes can be predicted by the sum of player levels on the team; Hwacha use is up 30% following last weeks patch whilst Mercurys are down 60%, etc.. A lot of pivot table action to produce snippets of data.
