Hi again, pizdin_dim,
...Why? In practical terms, is this true at all? Where are the tangible benefits if it were to do that?...
Quite baldly put:
OS software is (nowadays) mainly used by people not able to fork out the dough for commercial software like Movable Type for instance. Someone who can't or won't pay 200 bucks for a commercial software also is highly unlikely to pay huge amounts for hosting.
That's the core customer group of OSS like WordPress. Yes, I know all about the original background of Opensource. Yes, I also know quite many "because of the philosophy"-users of Opensource. Yes, I also know many coders who prefer using Opensource because of the access to the code.
BUT: the core customer group is the one I mentioned above.
If you have such a pronounced specific usergroup you had better heed its needs. It's truly that simple. And if you are an experienced software developer, you should have this adage written in fiery letters somewhere atop your workspace.
We wouldn't be getting such support posts here (and more and more often lately, by the way), if this weren't the case. And no, I am not under the impression that only a few are complaining or having problems. If you read the forums closely, there are many performance and ressources related tickets here. Decidedly more e.g. than with Nucleus and TP (whose forums I also follow).
It's also not as if that problem wasn't known among webmasters, as one such I have read many complaints over the past year (especially since WP2.0 surfaced) about these issues. They tend to stick to one's mind. WP still hasn't come back to first choice and it won't if "clunkiness" and "ressources-eating" attach themselves to its name more and more.
I like WP and I have defended it quite a couple of times and suggested it even more often, inspite of that "Google-thang" and the constant niggling between WP and TP, both of which really caused lots of people to backpaddle. If non-usability for the core usergroup is added to that...
And it's not necessary. A twist of mindset is all that's needed. To know one isn't as superior as one assumes, or in other words, a bit of humility in that respect, won't do any harm, que no? The moment one accepts the above facts and sets forth to deal with them, that's the moment you really better things.
