Apologies if mentioned above. Using android default browser. Couple of use cases that looks like haven't been considered.
1. Opening stories in new tab. I like to open the main slashdot page, browse down the stories, then as I see a story I like long press on the story and choose to open it in a new tab. This preserves my place on the main page, and I can reviews the story/comments in a new tab. Then close it when I am finished. Currently cannot long press on anything. Appears that each story summary on the main page has no 'links' as understood by the Android browser, rather some sort of screen area that cannot be opened as a separate tab.
2. Back button does not work. Seeing as I couldn't open stories in a new tab, I pressed to open a story. Naturally as with any browser based application, when I had finished, I used the Back button to return to the main Slashdot page. This resulted in slashdot disappearing altogether! I guess you are using dynamic loading of content. If you don't want this to work in a browser, then create your own client side application with it's own functionality. If you expect this to work in a browser, then for god's(gods,noodly) sake RESPECT THE WAY THAT BROWSERS WORK!
