I searched gis.se and found a *two year old* answer to a problem I have today.

But may be the *old* answer is not a good answer *today* because:

 - technical changes in the tool (proposed in the old answer)
 - license changes in the tool (proposed in the old answer)
 - there are new tools (not exists 2 years ago)

What should I do to get an up-to-date answer?

Example:
I am looking for a (stand alone) tool to convert raster (e.g. tiff, jpg) to ECW. I found a [two years old question with an answer][1]. The SDKs available from ERDAS are still read-only today. But perhaps there are other tools to convert to ECW today?

So the old answer is not *wrong* today. But there may exists *new/better* solutions for the problem.
