Nothing wrong at all, quite the opposite.

I like it a lot, and it makes me happy to see someone using the ligature of "e t"[0] ("&") not only as "and" but also as it's original "et" in the abbreviation "etc".

To me it reads like someone playing with words in a fun way, which is not that common in my parts of the internet

I was trying to express appreciation.
