In a 2010 piece for the Chicago Sun-Times, he writes:
My rules for Twittering are few: I tweet in basic English. I avoid abbreviations and ChatSpell. I go for complete sentences. I try to make my links worth a click. I am not above snark, no matter what I may have written in the past. I tweet my interests, including science and politics, as well as the movies. I try to keep links to stuff on my own site down to around 5 or 10%. I try to think twice before posting.
Ebert’s rules are my rules as well -- although, I do use the occasional “LOL” when appropriate.
Moreover, Ebert’s feelings towards Twitter mirror my own:
I vowed I would never become a Twit. Now I have Tweeted nearly 10,000 Tweets. I said Twitter represented the end of civilization. It now represents a part of the civilization I live in. I said it was impossible to think of great writing in terms of 140 characters. I have been humbled by a mother of three in New Delhi. I said I feared I would become addicted. I was correct.
Twitter is now a part of my daystream. I check in first thing every morning, and return at least once an hour until bedtime.
Before joining in June 2010, Twitter made no sense to me. Fast-forward almost three years, and Twitter is something I can’t live without. One of my most beloved apps ever is a Twitter client (Tweetbot), and the friends and connections I’ve made have made the service even more invaluable. While I don’t agree with Twitter’s business practices (especially towards third-party developers), I’m totally in love with Twitter as a service. So great.
