Apex Publishing: I love Apex Publishing. They support new and emerging Scifi authors along with established authors. They have open submission for their magazine and themed calls of submission. They pay $.06 a word, they have awesome art and interesting themed prompts. I guess you'd consider this blog inspiration fodder?
ProWritingAid: Beyond offering an AMAZING software series (see my personal experience here and also enjoy as I compare this service with peers) their blog suggesting other software applications, offering grammar/editing advise, and also supplying writing/plot structure is very enjoyable.
Scifi Monkeys: They have a lot of interesting reviews and conversations surrounding all current Scifi material. They also hold a "Seasons" call for submissions for those looking to write/submit
