I asked a question on Twitter: "An example of a non-monetary gift you couldn't accept from a company you cover? Why?"

Some of the answers...

Michael Calore: "copy of shrink-wrapped software i didn't review, comp tickets to a show/concert sponsored by a company i write about often"

Janet Ginsburg: "at businessweek (a while back) strong rule re no gifts. kept things clean. sm conf swag (pens, bags) but that's it."

Doug Levy: "just as physicians are inadvertently biased by trinkets like drug co pens, reporters need to vigorously avoid potential bias."

Freda Moon: "I was taught to accept no gifts from sources. None. Not tickets. Not a meal. Not even a cup of coffee. That last one can be hard."

Megan Taylor: "Tickets to sporting events. Reporters are supposed to be objective and accepting gifts compromises that."

There seems to be a consensus here.

Now a followup question.

Can you accept placement on Twitter's Suggested Users List if you are a journalist who covers Twitter?

Please this question is only for journalists.
