This is fascinating to me.
1. The gate agent was following the rules. Maybe a bit too rigidly but still, following the rules.
2. The guy must have used #southwest or something but someone at Southwest Airlines picked it up in real time and called the gate. Amazing.
Obviously everyone who publishes anything online, and Twitter is a publishing platform, needs to be careful of what they publish. I don’t know how many people were following this passenger but if he used a popular hashtag, like #southwest or whatever Southwest Airlines uses, his tweet might have been read by thousands if not tens of thousands of people very quickly.
I may be ignorant, but I tend to think that many on platforms like Twitter have no clue that their tweets might be read by a larger audience than the people who follow them. Between hashtags and retweets things can go viral very quickly.
Careful what you tweet.
