Nice site, it works well on mobile, which is a bit of a pleasant surprise when it happens from personal blogs etc.!
FWIW the Twitter feed from, I assume, people you follow is a little odd though - it's not immediately clear that it's not you, nor about the article being viewed, which it doesn't necessarily have anything to do with, and it includes replies to threads. At the time of writing the top one is recommended reading that's 'racist from the start'.
Yeah, it bleeds a bit too much on mobile - younger brother passed away recently and I shoved the site out the door before heading back home to be with him. Desktop view has it more marked as separate content - e.g, that tweet is actually a Retweet with a comment, which is kind of a pain in the ass to handle from Twitter's API. Should find time to clear it up a bit I guess.
Site works well on mobile because I cannot stand sites that don't load quick + layout well on mobile, and considering the general content I post, I'd expect the audience to have the (relatively) same pet peeve.
Looking at the feed you should see if it's possible to exclude any tweets that begin with "RT" (retweets) or the "@" (replies). This way only posts you write should show in the feed, would make it much cleaner as without the full conversation contexts those other messages make no sense.
The GitHub activity feed is pulling in every comment you make, see if you can filter that to only show pull requests you've created to showcase your work. Maybe also include commits to your own projects if the commit length is more than a certain number of characters to filter out the small updates.
Heh, I should be clear: I consider the aforementioned Tweet/RT issue a UI/UX thing, it's otherwise working as designed.
I'm perfectly happy showing my @replies, rando GitHub activity, etc. Nobody is actually reading that sidebar, short of a select few - I like having that junk indexed in search engines attributed to my own domain.
