It's fine to state where you work if:
- It's relevant to the question (i.e. the question has to do with a particular application at work).
- You're at an industry/trade show (where "where you work" is more important to fellow attendees than "who you are").
- It provides information the speaker needs (i.e. so that she'll know you're a colleague/partner/competitor).
It's not okay if:
- You waste any more time on your employment than "I'm So and So, developer at Initrode, and I'd like to know..."
- You're going to hijack the time to talk about your company.
- You're trying to "get some free marketing".
Is it okay to say where you work - the name of the company? Or is it better to leave it out? Can it be considered rude and something like trying to get some free marketing for the company? I am asking because I am not sure, and I heard both opinions so far...
