Brian Solis reminded us that the NFL has effectively banned Twitter use by anybody at a stadium on Game Day. But that doesn't keep big companies, small businesses and guerrilla marketers who use Twitter as part of their social advertising and marketing strategies from Tweeting to the larger audience of Tweeple watching games at home or at sports bars.

With wall-to-wall holiday football approaching, the same opporunity presents itself with NCAA bowl games and the big BCS series. Whether you're selling software, sauvignon blanc or shoes millions ofviewers with Twitter enabled handsets are out there on any given gameday ready for your next mobile blast. Here are nine guide and talking points for those passionate about Twitter as a sports marketing utility.With companies spending millions on prime time adspend, Twitter offers a cost-effective utility and a great way to develop an effectiveness baseline and to have fun while doing it.

1. Be your own clock manager. NFL teams spend millions each year on salaries for assistant coaches who are "clock managers" who get paid for telling the head coach when to call a time out (that is supposed to give the team a strategic advantage and provide the network with advertising time). Most of them, particularly the Jets, the Browns and Silicon Valley's darlings, the 49ers, do a terrible job of clock management. Don't wait for the coach to drop the flag to send your message during a time out. Send your Tweets during or after dramatic action and link your message to the outcome of a key play. Action stops when the linesmen moves the chains. No time outs left. Quarterback spikes the ball to stop the clock. Tweet.
2. Blowout games are an opportunity. Announcers are instructed to keep the chatter competitive and balanced but multi-game surfers usually click away. The loyal fans stay. This is a great audience space to promote conversations among loyal fans about brand loyalty that can go viral.
3. Avoid Tweeting about gambling issues, point spreads, over and unders. This is the #1 known reason the NFL has banned Twitter use at stadiums. Leave this issue with the huge sports betting industry that prospers on the Web. They have the deep pockets and connections to deal with the battalion of ex-FBI folks and other intestigative types who handle this stuff for the NFL and listen to ESPN and other sports networks on TV and web radio to develop the right vocabulary.
4. Keep your Tweets short so they can appeal to an attention span of 5 seconds.
5. Use Twitter lists and company Twitter data bases as target audience. Tailor your key messages to particular market channels when required
6. If you have the budget, use one or two social media monitoring services to develop a data baseline.
7. Be transparent and let the audience know who you are and what you represent and
8. Focus your message on large groups of people rather than an individual. Millions are watching the event you are Tweeting around in every corner of the world.
9. Use the free gameday dashboard offered at the top of NFL.COM to track the games and plan your Tweeting strategy for the day. Red zone alerts, big play alerts, come up instantly on your screen. This is a fantastic free utility that gives you a view of all games in real time.
