He's quite active on Twitter:<p><a href="http://twitter.com/paulg" rel="nofollow">http://twitter.com/paulg</a><p>Other than that he's probably just enjoying spending quality time with his young family after a relentlessly busy few years.
He's enjoying time with his kids (source: Twitter). My fav tweet - "If there is anything in the world better than being spontaneously hugged by a 2 year old, I haven't found it in 49 years."
During YCHacks he and Jessica came by the YC office with little kids. I was too busy finishing up our app to pay attention, but the two times I looked up, he was carrying a little one around the office on his shoulders.
It's actually been 137 days since he made his last comment on HN:<p><a href="https://news.ycombinator.com/threads?id=pg" rel="nofollow">https://news.ycombinator.com/threads?id=pg</a><p>However, he is very active on Twitter
By the way, I noticed that a lot of popular geeks who we (or me personally) look up have started young families. Probably just confirmation bias. But it's nice to see.
He's designing an even better Lisp dialect in which lambda is spelled f (down a full 50% from fn!) and let bindings do not require any parentheses at all:<p><pre><code> (let a 1 b 2 c 3 (+ a b c)) -> 6.
</code></pre>
Note how there can only be one form, otherwise it is ambiguous. But when you have two or more forms in a construct ("implicit progn"), all but the last are evaluated purely for their side effects (pun intended): it is imperative programming, which this new form of let nicely banishes.
