Today marks a turning point. In addition to being my first day as a member of [Clojure/core](http://clojure.com) and a [programmer of record for Relevance Inc.](http://thinkrelevance.com/blog/2011/03/02/relevance-turns-30.html), it also represents my last day as a paid [Scala](http://scala-lang.org) programmer. I discovered Scala in mid-2007 and have used it professionally since early 2008. Needless to say; I have enjoyed my time working with Scala. In many ways it is a beautiful language and I credit this beauty almost entirely in preserving my sanity after years of full-time Java work. I have found the community to be intellectually rich, and hold in high regard many of its strongest advocates and luminaries.[^adv] I wish that I could have been more involved, but at least I was able to release [Baysick](http://github.com/fogus/baysick), and for that I would like to offer my deepest apologies. I plan to follow the language to the best of my ability, but as one might imagine, my time will be spent on Clojure development and advocacy. As a consolation[^baysick] (to myself mostly) I would like to offer my notes on Scala collected over 3+ years, styled as a "[Pseudo-annotated Scala Levels](http://www.fogus.me/thunks/scala.html)". Thanks to everyone involved in Scala, and especially to Dr. Martin Odersky for his leadership and for once [indulging an admirer](http://blog.fogus.me/2010/08/06/martinodersky-take5-tolist/). It has been a blast.[^blast] Fogus signing out. :F [^adv]: Including, but not limited to: [Paul Snively](http://twitter.com/psnively), [James Iry](http://james-iry.blogspot.com/), [David MacIver](http://www.drmaciver.com/), [Daniel Spiewak](http://www.codecommit.com/blog/), [Jonas Bonér](http://jonasboner.com/), [Viktor Klang](http://twitter.com/viktorklang), [Paul Phillips](http://twitter.com/extempore2), [Josh Suereth](http://suereth.blogspot.com/), [David Pollak](http://twitter.com/dpp), [Alex Cruise](http://twitter.com/alexcruise/), [Dean Wampler](http://programming-scala.labs.oreilly.com/), [Alex Payne](http://al3x.net/), [Bill Venners](http://www.artima.com/weblogs/index.jsp?blogger=bv), [Lex Spoon](http://www.lexspoon.org/), [Timothy Perrett](), [Tony Morris](http://blog.tmorris.net/), [Steve Jensen](https://github.com/stevej), [Stephan Schmidt](http://codemonkeyism.com/), [Erik Engbrecht](http://erikengbrecht.blogspot.com/), and [Debasish Ghosh](http://debasishg.blogspot.com/). [^blast]: I have both positive and negative opinions on Scala, but this is not the time to go over them. However, I will say that my opinions are indeed mostly positive. [^baysick]: Up until the moment of accepting the position with [Relevance](http://thinkrelevance.com) I was fully devoted to submitting an abstract (thanks to a successful first draft) to [Scala Days 2011](http://www.scala-lang.org/node/8866) for a silly talk on [Baysick](http://www.scala-lang.org/node/1403), but alas...
