I always have to remember to mentally insert
"in my opinion" in front of Stabbey's comments, because he never does.

That would be kinda redundant since basically everything someone posts is "in their opinion".

Feel free to copy my signature
I like to use phrases like 'in my opinion', 'I believe that' or 'well the way I see it is' when I feel it helps convey the tone I am intending, or to clarify statements that I suspect people may interpret as assertions of fact.
