Frankly, I am a bit disappointed that you profess to being a noob, but 
then when you encounter a factual argument why adding elevation data to 
OSM does not make sense, you translate this in your head to "the person 
writing this doesn't like the idea".

This is not a question of personal preference. OSM's data model and 
editors are not suited for it.

Mike wrote in a follow-up that plotaroute.com already knows about 
elevations. I assume you knew this already but were unhappy with the 
precision of elevation data used by plotaroute.com, and hoping to 
improve that by editing OSM. But these elevations do not come from OSM 
and it is extremely unlikely that plotaroute.com would take elevations 
into account that are recorded in OSM. Instead they will be using a 
third-party set of elevation data, e.g. the NASA SRTM data set (as 
explained in the response in which one Frederik Ramm "didn't like the 
idea").

This means that even if you were to add more precise elevation data to 
OSM than SRTM, it would very likely not have an effect on what 
plotaroute does.

Cheers
Frederik
