Hey folks, been a long time but I thought I'd share a Dresden files (and Fate) inspired project I've been working on. Now's the time, after a few tens of hours of effort, to find out if someone's already had the same idea and done it better

The pitch: Mobile friendly webapp where users can post Aspects to share, and tag them with single word tags, then browse or search for them.

You can check it out here: http://aspectinator.appspot.com/

Feel free to PM me feedback, comments, questions, requests. I'm working on it pretty regularly, and will continue to push patches and general upgrades; there should not be any further changes to the data model, so whatever content gets added will persist across any upgrades, which will be UI related primarily.

Current issues
-There's still some clunkiness about the UI while I port the rest of it from Jinja templates with WTForms to Angular.
-Only Google users can log in today, although anyone can browse/search. If there's enough interest I'll set up Oauth for Facebook, MSN and Amazon.
-There ain't no danged content. I seeded it with some top level type tags, but I haven't input but a few aspects as samples.
-User profiles are quite barren. You can't see much except stuff you've liked.
-The URL doesn't match the name and they are both kinda dumb.
-The UI works fine on most mobile devices but is not amazingly polished or anything.
-It's on a free GAE account, so if people love it it might crash - if people use it that much I'll remedy that.

Disclaimers
-The only info the tool stores about you is your Google account ID, what you've liked, what you've created and when you've done everything. If you edit something, it'll note that you were the last one to do so (the number of edits you can make are pretty minimal.
-I will almost certainly break stuff from time to time; my programming chops are pretty dull and just about every piece of the technology used is new to me.

Nerd stuff
-Written on Python for Google AppEngine, using the Ferris webapp framework combined with AngularJS and Bootstrap 3, and just a few dollops of Jquery here and there where Angular couldn't get the whole job done.
-Data stored in the Google object datastore.

The best way to do this, done in other FATE games, is to give the boss multiple actions or make it a "modular" creature-- it's narratively a single creature, but is built like multiple characters and has multiple actions.  A classic example is a Dragon.  You'd build its' tail, it's maw, and each of its arms/claws as separate characters.  They each get an action during each exchange (maintaining action economy) and they (probably) share stress boxes between them (at the cost of remaining in the same, or nearby zones as you'd expect).  Stat the skills of each piece as makes sense. 
Maybe each piece has different Aspects and players can declare which they're attacking for max benefit.  "The tail has the Aspect, 'Not Being Watched,' right?"
Maybe the claws make grapples while the tail maneuvers or establishes blocks and the maw bites or uses a "breath weapon" of some kind.

Dragon (4-part)
Physical Track:
_{(Claws provide:)} [][][][] _{(Tail provides:)} [][] _{(Maw provides:)} [][] (+ Extra for the Endurance skill rating each piece might posess)
etc.

Already tougher, and it hasn't even taken Toughness (on any of its pieces), yet.
Perhaps allow people to take out pieces of it as you go along-- after all, if they hack at the tail exclusively, it's gonna get chopped off / wounded beyond use, right?

Be creative -- Think outside the box.

This is awesome. I can't believe I didn't think of that one. I have taken the approach of having my infrequent 'big bad' things have multiple actions as needed (say, claw, bite, breathe fire) to keep things exciting and spread the damage around.

Giving different 'actors' different stress boxes! Great.

Off-topic a little but my tendency with "there are 1000 zombies!" is to make it an aspect that I invoke for effect (usually something like 'everyone suffers a level X attack of some sort') until they counteract it with the appropriate skill challenges or something. Seems more cinematic to me than tracking the exact number of zombies and stress boxes and all that.

Regarding NPCs, I don't feel any compulsion to make fully populated skill pyramids for NPCs. Usually I just pick out the few skills they need and hand-waive the rest until they come up. Aspects are the most important part of NPCs for me and so I focus on that. If they've got a bunch of powers I tend to note the important ones, and if I feel they should have a particular stunt I'll note it and stick with it.

Sometimes I'll do something like "weapons 5, athletics 4, everything else assumed to be 2, roll out!" if I need to short hand something.

Seems like I wind up with maybe a handful of fully statted NPCs at best.
