I say there is nothing wrong with meeting an internet friend IRL, BUT you should exercise ad amount of caution.
Make sure you know the person pretty well (known them for a period of time, voice chatted, skyped, know what they look like, what they do etc.)
If you're meeting someone for the first time make sure you do it in a public place, preferably take a friend. Safety in numbers.
Your friend probably isn't dangerous, and certainly will understand precaution.
Meeting internet friends IRL can be awkward to begin with, people often have different public personas. Just hang in there, you'll work it out!
My mate and I have met IRL, the internet is a fantastic tool for meeting like minded people all over the world! ^w^
