• Title - many attendees will read only the title of your talk. It should contain at least one or two nouns that convey the topic, language, technique, or whatever you are primarily talking about. Many speakers submit titles that are two parts, separated by a semicolon, dash, colon, comma, or parens. In almost every case, the title is better if you delete one of those parts. Likewise, many speakers submit snowclone titles like "The Hitchhiker's Guide to FOO" or "FOO is the new BAR". Please try to avoid these.
• Description - should sell your talk to attendees (and reviewers). The abstract should answer the attendee's question "Why should I attend this talk? What will I learn?" The sweet spot is 3-5 sentences. An attendee may be comparing 5 concurrent talks and they want to know whether it's relevant to them.
• Reviewer info - this is where you can privately communicate the next level of detail to reviewers. Reviewers are trying to determine what main points you will make, and whether you are capable of delivering on the expectations in the abstract. If the abstract says you'll learn 3 techniques for XYZ, list them! If you don't, we will assume you don't have a plan or can't deliver and move on to the next talk. On the other side, do not deliver the full text of your talk here, just give us one more level of detail.
