Has the site layout changed in the last 12 hours or so?
Used to see my own username and vote counts when browsing which would also serve as a link to my own profile, however that's been removed/replaced and now needs the left swipe sidebar navigation for that purpose - which doesn't always work, meaning it's not only a far less visible option but also far less effective.
There's nothing in the last 2 weeks on the changelog win [unless I've misunderstood what that is meant to be], and given this wasn't an issue the last time I checked here on mobile [under 14 hours as I remember checking a thread that is now that old] something seems to have changed with no notification.
Yeah if it were me I would have omitted those other categories from the sidebar until they were ready to launch.
I tend to be a bit lenient on the dev of the site overall, as it's pretty much a one man team doing all the tech work on the site. We aren't talking about a user experience team that has spend 6 months looking at PowerPoints about a redesign and then some Indians that make it for them. I think they are doing pretty good to have gone from nothing to handling millions of pageviews a day in a year despite being dropped by several hosts and targeted by DDoS attacks. So, I just temper my expectations a bit with that in mind.
