How often should people post new items on Twitter?

“Quality is more important than quantity,” says Kevin Gilnack, of the nonprofit group The Providers’ Council, “Make sure you’re sending useful, relevant information, and do your best to spread it out. Also, try not to tweet about your own organization on an average of more than once every seven or so tweets. You will also find your followers engage you more if you engage them.”

Mr. Gilnack’s advice came in response to an effort by The Chronicle and the social-media expert Beth Kanter to get advice from lots of experts after Ms. Kanter spent more than two hours answering questions from Chronicle readers about how to effectively measure their efforts on social-media sites like Twitter and Facebook.

And after exhausting her fingers and, for sure, her brain for more than 120 minutes, Ms. Kanter, author of the popular blog Beth’s Blog, wasn’t able to get through all of the questions thrown at her by Chronicle readers.

But instead of letting those questions go to waste, Ms. Kanter posted the unanswered queries on her blog and invited her readers to offer their own advice.
