Dennis Kennedy and Tom Mighell enter the realm of apps and plug-ins. Also known as web extensions, browser apps, add-ons, and bookmarklets, these additions to web browsers are made to make your Internet browser experience more efficient. Learn your hosts’ favorite web extensions when browsing for leisure and for work, and how to manage your apps and plug-ins so they don’t slow down your browser speed. The second half of the episode turns toward Internet communication, more specifically, how Twitter users are creating hashtags to express their moods in posts and how this changes the meaning and use of the hashtag.
