Does it make sense to post anwsers which solve posted problems by offering a completely diferent approach which in essence still solves the problem.

But im talking in the sense, that someone is trying to achieve something in a way that is cleary a bad one, or maybe a deprecated - non future proof, or something similar. And for example, you know how to fix this in the context of his/her current solution, but you also know a different - better way, either through different software, other data formats or whatever. Should you just tell about the quick patch or try to present your approach?

What's your opinion on this?

I think this is a great approach: giving someone a good answer to the problem they really have, rather than a good answer to the problem they think they have, can make a huge difference both to them and to future readers.

Doing this usually requires an initial dialog, via comments, in which you--the potential respondent--seek to clarify and better understand what the problem really is. You might also need to ascertain what resources (such as software and conceptual understanding) are available for the solution; for instance, it might not help much to propose a raster-based solution when the O.P. does not have access to raster processing software.

+1 I would want to learn how to do things correctly if I'm approaching a problem the wrong way. –  underdark Nov 28 '12 at 18:55
