I received my Ph.D. from the University of Pennsylvania in 1998 and I have been teaching since then at SUNY Oneonta for 1 year, at Shepherd University for 5 years, at Tennessee Tech for 2 years, at Lane College for 1 year, and this year I taught at the University of Massachusetts Lowell. My research interests include Representation Theory and Combinatorics.

The most important, probably, would be better integration with LaTeX, including conversion of formulas not only from Maple to LaTeX (which, by the way, is unsatisfactory now), but also from LaTeX to Maple, and using LaTeX in plots. Also, accessing Maple from LaTeX (something that Sage has), and a possibility to write articles (including, say, tests for Calculus classes) inside Maple, with including Maple calculations in them.

Related to that, plots export to pdf also would be helpful because most people switched from ps to pdf by now, and for that pictures in pdf format are needed instead of eps.

Plots export to png and svg, for including them in web pages, also, without doubt, would attract a lot of people.

Mathematical features - start with all that GAP (included in Sage), PARI (also included in Sage), Singular (also in Sage), Sage and Magma have. Combinatorics, Algebra, and Number theory most importantly. Then - what Lie and Schur have (for Representation Theory.) Geometry also would be nice.

I wouldn't call this site a counter-example. Not that many people participate on the advising side - only maybe 5 or 10. The number of mathematicians is even less. Compare that with old MUG group in which hundreds of people participated - that gives another example and not a counter-example. The Mathematica newsgroup is much more representative.

Now, it is not something new. In particular, not only me (as well as other Maple newsgroup participants) posted several times about that (a wrong direction of Maple development) starting 5-6 years ago and maybe even earlier, but also one of Maple founders, Gaston Gonnet. We all were ignored.

It is easy for us, but it is hard for programmatically and/or administratively challenged people.

It should look the same if you apply lprint to it.

There is no default vertical range of 2.

Take a look also at

plot(1-x,x=-10^(-7)..10^(-7));

and

plot(1-x,x=-10^(-6)..10^(-6));

The plot height shouldn't be 2. It should be the same as width, and the derivative at 0 is -1. By the way, the jump also occurs with Classic, just with different bounds, for example, for

plot(1-x,x=-10^(-7)..10^(-8));

It looks normal in Standard though.

It should look like 1-x, not like 1. In general, cos(x) in this situation is not needed to show the problem. The same problem occurs with y=1-x. A horizontal line in Classic, which is wrong, and a jump in Standard.

MmaTranslator:-Mma:-RealDigits seems to be not able to handle (positive) numbers less than 1,

MmaTranslator:-Mma:-RealDigits(0.11);
Error, (in MmaTranslator:-Mma:-RealDigits) Maple 
cannot handle the function RealDigits with arguments (.11)

Also, the base is not implemented,

MmaTranslator:-Mma:-RealDigits(1.1,2);
Error, (in MmaTranslator:-Mma:-RealDigits) Not 
implemented case of RealDigits with 2 arguments

Isn't A[[v]] a shortcut for LinearAlgebra:-SubVector(A,v)? Why use LinearAlgebra:-Subvector(A,v) if A[[v]] does exactly the same, and much shorter?
