Here are some stream of consciousness notes on navigating Federated Wiki using a mobile device (Samsung Galaxy S5 using Google Chrome).
I went to http://fedwiki.andysylvester.com , saw the Welcome Vistors page. I was able to log into the site by clicking on the lock symbol at the bottom of the page. After the click, the Twitter app authentication page appeared, then eventually the Welcome Visitors page appeared again with the padlock open instead of closed.
=== Scrolling on a page ===
When I tried scrolling down by doing a swipe, many times page elements started moving around instead of the page scrolling. The most reliable scrolling method was to tap on the right side of the page (a scroll bar would appear), then pressing on the scroll bar and dragging up or down.
=== Clicking on links ===
When I clicked on links within my site, many times the paragraph element started moving around. I would tap in many places on or around the link, but had great difficulty in selecting the link. Links that were at the beginning of the paragraph were the most successful in navigating to the next page. The best place to tap was the area to the left of the beginning of the link.
For links that were external to the site, the link would open in a new tab. Another alternative was to press and hold the link. If the link had been selected, Google Chrome would open a dialog asking how to open the page (a new tab, etc.).
=== Other discoveries ===
While looking around at Ward Cunningham's Tips for Administrators page, I found a glossary page of wiki actions and definitions. This was excellent information, but how would someone find this? There needs to be more effort spent on surfacing this information.
=== Browser differences ===
I decided to repeat testing using Firefox for Android, and found that I did not have any of the navigation problems that I saw using Google Chrome for Android. This is good news, but I would like to know why Firefox is working better than Chrome.
