On the whole, I tend to agree.
Until recently, I thought that you basically couldn't get to meta unless you already knew about it; I would always go there either by manually typing the URL into the address bar or by navigating to a user profile page and clicking on 'meta user'. Now I've discovered the link in the help menu, which is a very useful and quick way of getting to meta - provided you know it's there.
So yes, it would be nice to have a clearer link to meta from the main site (and vice versa). But you're not going to get this implemented by asking on the SFF meta site. If such a change was made, it would be done across the whole of the SE network, so the right place to post such a feature-request is main meta (where it'll probably be closed as a duplicate, since I'm sure someone has had this idea before).
On the other hand ...
... people who already know about meta will also know how to get there: in the worst case, by typing in
meta. into the front of their address bar manually; or by using a shortcut such as the dropdown menu, if they know about it.
The main advantage of having a clear and direct link would be for people who don't already know about it. So put yourself in the shoes of someone new to SE who doesn't know there's a 'meta' site for discussing the site itself. If they find a bug, or want to ask about some policy or about how something works in the SE system, what are they likely to do? They'll look around the front page and see this button saying "help". Then they'll click on that and most likely discover the meta site. Problem solved.
The existing methods
Here's a nice screenshot (complete with hand-drawn circles) to demonstrate the currently available ways of getting to the meta site from the main front page: you can drop down the "StackExchange" or the "help" menu from the top bar, each of those have a link to Meta, or use the links from the right sidebar to featured articles on Meta.
