As far as i am for promoting indie games, the Project Zomboid is already well known compared to most of other Indies (it is a great game in itself imho).
It might need defending due to lack of software updates but the Devs themselfs already explained the reasoning (pretty straightforward and they have my support).
Game is fun in it`s current state although can get boring (this will be remedied with an update in future).
Good luck with your blog (didn`t have a chance to read/view it yet), i hope you`ll stick with pursuing the target of getting the games more popular as opposed to making yourself popular
There are some other games worth promoting, fighting on greenlight:
My personal favourites, order purely alphabetic:
Frozen Nightmare (still alpha, no GL), Mobiloid, McDroid (beta, almost finished), Rawbots (Beta, No GL), Recruits (Beta), Salvation Prophecy, Underrail (beta), Xenonauts (Beta, No GL)
