Sorry, but this announcement was frankly too little, too late. I had looked at the Wikimedia blog post, the Noun Project blog post, the eventbrite page, the talk pages of the event pages in mediawiki, meta and wikipedia (btw, why so much duplication? where was the central hub?) and there was nothing even suggesting that remote participation would be possible, or that a hangout could be expected. This is even worse considering that it was asked a while ago (
http://lists.wikimedia.org/pipermail/design/2013-March/000423.html) but nobody seems to have answered.
Apart from that, where were the results posted? All I found were pictures from the event, spread across several categories. I've collected them on
http://commons.wikimedia.org/wiki/Category:Iconathon_2013 and cleaned up the other categories they were polluting (e.g. Category:I !!). I would expect the results to be uploaded to
http://commons.wikimedia.org/wiki/Category:The_Noun_Project but so far I haven't seen any new icons there. Is this coming soon?
Self-answer, after doing a little research: "Afterwards, The Noun Project will take the pen/paper sketches and have their vector artists render them in SVG. They will be released about a month after the event" — from
http://lists.wikimedia.org/pipermail/design/2013-March/000421.html. Yet this wasn't mentioned anywhere in any of the page I listed above. A "results" section would be most welcome for those who weren't able to participate.
Related, for anyone interested: I recently came across interesting resources for the kinds of icons that the Noun Project seems to focus on, and tried to organize the categories in commons to make them more findable:
http://commons.wikimedia.org/wiki/Category:Plain_black_icons (and subcategories) and
fontello.com (font-based icons, all of them freely licensed).
ps - I don't understand why this announcement wasn't also posted to the design mailing list. I'm CC'ing it.
