What does IMHO mean?

In my humble opinion

Example: IMHO Fluther is the best community Q&A website in the multiverse.

or in my honest opinion

@sferik… the multiverse? that’s like the blogosphere right?

For some dumb reason I thought “honest” opinion, but I think it’s humble now. I want some disambiguation for my acronyms.

It’s meant In My Humble Opinion from the beginning (as evidenced by the ancient-looking web design on the page I cited).
