Yes, that's exactly what Lorem Ipsum is intended for.
While I can imagine there being some usecases in which you'd want to actually test the readability of some design and maybe provide some text that a user can actually read, in most cases you don't and you use Lorem Ipsum to keep the client from reading the text.
One thing you definitely don't want to do, during the design phase, is putting text there that is almost but not quite a finished version of what is actually going to be there. Because that way you guarantee that the client will be reading the text and (even involuntarily) come up with all sorts of things that are slightly wrong about the text and could be improved, which is all very useful (maybe), but not if you're looking for feedback on the design, which is when you use Lorem Ipsum filler.
That said, there may be a few use cases where this "meaningful but unrelated" filler is appropriate, but it's most definitely not "better" than Lorem Ipsum. Nor is "Lorem Ipsum is lame" a valid criticism in these use cases.
You are coming from the stance that content, i.e. words, is separate from the design around it. I'm saying this is bullshit and that words/content are the most important parts of the design.
Using a fake language and text that you don't read takes away from that. Even using my classicipsum.com generator kind of takes away from that; but it takes away from it on a smaller level. I try to use the actual content and copy for a site, but that's not always possible (like I said, for example, when I'm making a WordPress theme). Hence classicipsum.com
Content is not there to just "fill space". Content is the reason people are coming to a website. Long written content, like blogs, is important to keep in mind when designing for some projects.
For me, I often design WordPress themes, which relates to blogging. Using real content like this is better than just having fake text that isn't even in the language a client will be using.
Ideally I wouldn't use filler text at all, but using at least actual English words prevents me from viewing the content as just something to "fill the space".
Not what I said. Filler text is there to fill space when you don't have the proper text - it's useless, it doesn't have meaning, it's likely to change in the next 5 minutes. Real content is there to be on the final version.
