    Don't be shy, what was your matlab learning curve, how many years or months, what were the difficulties to begin with.
    I think that the answers would be most valuable for new users, maybe you can also tell us the tricks that allowed you to master some parts or all matlab.
    Now it's your turn...

    Some Foreign Matlab forums

    Which Matlab related forums and newsgroups do you use beside MATLAB Answers? Which languages do they use? Which advantages and unique features do they have?
    Do you think that these forums complement or compete against MathWorks and its communication platform?
    Actually all answers are accepted.

    Dumb mistakes we make with MATLAB.

    O.k., admit it. Who has done this (or something that resulted in the same loss of info) before?
    >> laster
    ??? Undefined function or variable 'laster'.
    >> lasterr
    ans =
    Undefined function or variable 'laster'.
    D'Oh! I need a ERRORBEFORELASTERR function.
    What's one of your dumb MATLAB mistakes?

    What parts of MATLAB would you not miss?

    Are there parts of MATLAB that could disappear as far as you were concerned, things you don't need or which were "bad ideas" or which cause more trouble than they are worth in your experience?
    One suggestion per answer please, so we can see how other people feel about the same matters.

    What do you like about MATLAB?

    I use MATLAB most days (when I'm at work!). It makes my life easier, for many reasons, which is why I like it.
    What are the reasons you like it (assuming you do), and why?

    [DEPRECATED] What frustrates you about MATLAB?

    I love MATLAB. It is so quick and easy to write software to do what you want. It has excellent debugging and profiling tools. It is cross platform, making code easy to share (assuming the other people have forked out for the not-so-cheap license). It has interfaces to other software.
    However, there are some things about it that irk me. I'd like to hear from other people what things annoy them about MATLAB.

    Contributors metainfo: reputation and more

    As asked by Vieniava in "How to make a list of user's reputation?", some of us came up with interesting ideas on how to fill an updated list with the reputation scores of the contributors to Answers.
    I took the initiative to compile a public list of users with meta info:
    • position (desc ordering by reputation)
    • id
    • nickname (truncated to fit the page)
    • reputation
    • # of comments
    • # of questions asked
    • % accept rate
    • # of posts answered
    • # of accepted answers
    The code used to compile the list is available at the bottom.
    EDIT
    TMW team implemented a page with the metascores: http://www.mathworks.com/matlabcentral/answers/contributors
    Please refer to it and congrats to the team!
    Use this function to retrieve info from the link above:
    function [metainfo, elapsedTime] = metainfo(type,order)
    % METAINFO - Retrieve metainfo on contributors to www.matworks.com/.../answers
    %
    % METAINFO Retrieve data sorted by reputation in descending order
    %
    % METAINFO(TYPE,ORDER) Specify TYPE and sorting ORDER as
    % type : 'reputation'
    % 'questions'
    % 'answered'
    % 'accepted'
    %
    % order: 'asc'
    % 'desc'
    %
    % Examples:
    %
    % % Standard call (rep, disc)
    % info = metainfo;
    %
    % % Sort by question answered in descending order
    % info = metainfo('an','d');
    %
    % See also: URLREAD, REGEXP

    % Tested on R14SP3 (7.1) and on R2009b. In-between compatibility is assumed.
