Update routing.rst

[fatmuemoo]

Added a note to provide extra guidance when naming routes

[wouterj]

it's not meaningless, you use it to reference to the route (for instance when generating a route in a template or controller)

[fatmuemoo]

I concur. "Meaningless" is the wrong word. "Arbitrary" would be a better way of describing the route name.

I think we should move this to the last sentence of the next paragraph - so right after in your controller (keep reading). - how about:

The blog_show is the internal name of the route, which just doesn't have any meaning yet and just needs to be unique. Later, you'll use it to generate URLs.

I think if we do this (feel free to re-word), then we're in good shape!

We should at least avoid the first person perspective.

Thanks - updated my example above!

@fatmuemoo What do you think about my proposed change above? Can you update your PR? If not, just let me know and someone else can open a new PR with the tweak.

Cheers!

[fatmuemoo]

Sounds good to me, thanks

[weaverryan]

@fatmuemoo :) - ok - but can you also update your pull request with the suggested changes? I can also update it for you if you'd like!

Cheers!
