I pulled several parts of unused JavaScript out of what Mnikr is serving, leading to about a 60K reduction (yes, that’s after gzipping and minifying).
I’ve increased the time the feed grabber is willing to wait for feeds; you shouldn’t notice any additional load time, but some feeds that haven’t been loading properly, now will, or at least more often. (Twitter’s gone haywire, but that’s not my fault.)
I’ve added back @username linking in Twitter feeds, and added #hashtag linking as well (the latter to http://search.twitter.com, as Mnikr doesn’t currently process hash tags). Hopefully this will be useful to those of you who have asked me for it!
