Two radical (yep, bringing that back) flash stories that came out recently:
A bit of LA noir in Cold Storage by Michael Solender at Flash Fiction Offensive. That annoying guy who rents the storage space next to you? He's going down!
And from a horror site I've been getting into lately, Die, Baby, Die by Grant Wamack at The New Flesh. This piece oozes with creepiness and believable terror.
