My handwriting is apparently somewhat distinct. A friend of mine actually had me write out various stuff in it so he could try to create a font from it. It probably won't be very legible to anyone but me though.
I never understood the problem with '7's. Why the dash through it? I mean, I've got some weird ideas for how letters get formed, making 'the' look like '13' and other such problems. But when it comes to numbers, it's so easy to be precise. Just draw your damn top of the seven long enough, and it will be so immediately and obviously a seven that to mistake it for a one would require some mild mental retardation. I never understood why that was an issue.
And the same thing goes for 'Z's. Sure, it might end up looking like a '2', but... context? I mean, seriously. How many places can you think of where you wouldn't be able to figure a 'Z' from a '2'? Who the hell is writing 'Vene2ela'? And don't give me any crap about when you're talking in math - when it's critical in that sense, just sharpen the edges, and poof, built-in recognizability without extra slashes to make things look dense.
I guess I get worked up about stuff like that.
