Some big changes are in store for everyone’s favorite micro-blogging site: Twitter unveiled a redesign on Tuesday. So what’s new? The biggest change is that the site will now feature two panels: The left-side panel will feature the traditional stream of tweets; the new, right-side panel will display videos, images, maps, and “related content” from tweets that are clicked in the left-side panel. TechCrunch shows you what it looks like. The new Twitter also features infinite scrolling so you don’t have to click a “More” button anymore. The changes will be rolled out as a preview over the next several weeks.
