I'm not a pedant as I don't know grammar rules so I can't explain why this annoys me so much.
Recently I've noticed many work colleagues using 'I would' as filler in speech and text. E.G. 'I would recommend you sit down' instead of 'I recommend you sit down'.
I'm in Ireland but I hear it on British and American podcasts too so it seems to be a trend.
I often edit other people's writing and deleting the 'would' just infuriates me. I think it's the fact that someone is trying to make some clear and concrete into something that sounds vague and hypothetical ... But I don't know if there's any basis to that.
