That word, it does not mean what you think it means.

I’ve noticed a lot of spam and tweets lately that are grammatically correct, but do not quite convey the message the writer thinks they do. This post is a collection of my favorites—it will grow over time.

I work as a professional Web Designer / Developer in a reputed firm.

reputed
1. Accorded a reputation.
2. Supposed or assumed to be true.
3. Generally believed to exist, but that is not the case.

Pretty sure they meant reputable, but who knows.
