I don't publish articles on my blog until I've been able to fully proof-read it without any second-takes. You should always write for your target audience. If you need to use an uncommon complex word make sure it's context is clear for users without them having to look it up and don't constantly reuse it otherwise it looks unnatural and therefor unprofessional. If someone has a lower reading level they should still be able to read what you've written and be able to infer your more advanced intentions from the basic construct of what you have written.
So ultimately try to write using base low-level constructs that are emphasized by moderate-to-higher constructs and your point in your writing will be "felt" if not outright understood.
