I am currently an employee of LinkedIn. I receive a salary from them and I also own LinkedIn stock options.
Other than compensation from LinkedIn, I don’t accept any money or other gifts of value from any companies or individuals. I don’t accept speaking fees, consulting fees, honoraria, or trips. I don’t accept free, discounted, or loaned products. When I receive unsolicited gifts of value from companies or individuals in the scope of work, I give away those gifts.
When I speak at a conference or event, I generally do not pay a registration fee for that event. Some conferences also waive registration fees for that event for one or more of my colleagues or a traveling companion. Either my company or I pay my own travel and hotel expenses when I speak at an event.
I do not run advertisements or otherwise receive any monetary compensation from the operation of my website.
