>>why I need to blow up my static site today

You don't. If you think you would benefit from community features or interactive features, it may be worth it. If you plan on having a lot of different people contribute and want to control and streamline workflow it might help.

If you want to jump on the bandwagon, I don't think they're playing your song ;-)

Another thing to consider. I would think that for most pages of your business site, you would not want to allow comments (like do you really want people commenting on your "about us" page?).

So the way to get your feet wet would be to install a blog app in a subidrectory like

example.com/blog

And start experimenting there. If it increases traffic, visitor engagement, etc, then you might expand out from there. If it doesn't, you haven't wasted a huge amount of time converting your site for nothing.
