Plus is an internet magazine which aims to introduce readers to the beauty and the practical applications of mathematics. A lot of people don't have a very clear idea what "real" maths consists of, and often they don't realise how many things they take for granted only work because of a generous helping of it. Apparently, some people even have the idea that it's boring! Weird. Anyway, we hope that even if you're such a person now, you won't be after looking through one or two issues of Plus, and that you'll come back and read future issues as they come out. Plus provides feature articles, which describe applications of maths to real-world problems, games, and puzzles; reviews of popular maths books and events; a news section, showing how recent news stories were often based on some underlying piece of maths that never made it to the newspapers; a puzzle for you to sharpen your wits against; a lucky dip of mathematical curiosities; and opinions on various maths-related topics and news stories. We have a regular interview with someone in a maths-related career, showing the wide range of uses maths gets put to in the real world. And all past issues remain available online, which besides making for good browsing is, we hope, a useful resource for maths school students and teachers.

Try to make sure your question is of interest to at least one other mathematician ... the intended audience is professional mathematicians, mathematics graduate students, and advanced undergraduates ... Math Overflow is not a discussion forum ... Blogs and threaded discussion forums are a more appropriate place for discussions.
