I totally agree that there is nothing better for brand recognition and respect than having a presence on the web. I also agree that with that presence comes a huge responsibility to keep the brand in the most positive light.
In one of my earlier stops in my taxation career I came across some Twitter comments from a young lady who had started working in one of our US locations and in her tweets she was trashing the company and doing this while sitting at her desk.
I notified IT and she was removed from the company for conduct detrimental to the company.
Bottom line… Don’t be stupid. If you are supposed to be working from home or out of the office don’t update your facebook status. If you want to use your facebook account to post pictures of you getting drunk of half-naked, make sure it’s viewable only by your friends because you don’t want your potential employer at a law firm, CA office, etc. seeing you like that and letting it cloud their judgement of you.
