spnspringfling is posting! I'm reading my way through when I get a chance, but here are a few recs to start off with. I haven't even read close to everything that's posted though, so it's just the start.
As always, if you have any recs for things I should read, please put them in the comments!

Ignorance, (Sam/Sarah) Using a past character to highlight the difference in interaction between then and the fic time is always intriguing to read and this fic did that perfectly. Sarah is a great POV character on how things have changed for Sam.
Show Me My Heart, (Sam/Dean) I really love this one. young!Sam sees future!Sam and future!Dean doing things in mirrors wherever he turns and it's both hot and heartbreaky to see how much he longs for that future and hopes for it.

Sure to Lure Someone Bad, (Jo/Crowley) I love Jo so much in this piece, and dapper Crowley in the background also. Pardon my language but you know she's going to kick the shit out of him in short order (and then possibly something else). Great story piece.
The Book of Abel, (Sam + Dean gen). The Book is a character all of its own here, and the story is an intriguing take on current canon. Sam's obsessive and compulsive over rescuing Dean and that's just the way I like him.
ART
Please, can I touch... (Dean Smith/Sam Wesson) Is it just me or is it hot in here? Sam's in lingerie and domming Dean who is quite clearly loving every moment of it.
Punishment, (Sam/Dean). Solidly good and sad fic about what happens when it all catches up to them. The moments they share are as precious as they're brief.
ART
For Your Eyes Only, (Sam/Dean) Great colour scheme and sense of connection between them, and I can't stop staring at Sam's face, and that bright blue thread linking them together.
SPN RPF
Second Thoughts, (Genevieve/Adrianne). I'm a sucker for people being sensible adults and making sensible life decisions...and then throwing it away because damn, this matters too much. What I'm trying to say is, read this, because it does that perfectly. I would love to see more of this.
A Stargazer Am I, Jared/Jensen I am also a sucker for slow burn gradual relationships where both parties fall in love without even knowing it. This makes you root for them hard and then gives a pleasant shot of fulfilment.
Early Morning Yesterday, (Jensen/JDM) Charming Jensen being flirty and forward and JDM being a little overwhelmed and really into it, is apparently my jam. Who knew? This is unusual and calls out for a sequel.
Southern Hospitality, (Danneel/Jensen/Jared) Jared is in well over his head with Danneel and Jensen and I loved every second of it :D fun, light hearted and sexy.
