I'm afraid I never have quite got the idea of 'blogs'.
What's their purpose? To tell other how well you've done, what you caught your fish on, how big were the fish, what species they were, etc. And is the whole idea for as many people as possible to read these 'blogs'?
If that's the case, then why not write the blog as an article and send it to us?
Now whilst it's true that magazines can be very selective about the articles the reproduce, we on websites aren't tied to the amount of space we can commit every day/week/month and so are far more responsive to articles we receive. What we do like to see is pictures, Rufus was mentioned earlier here and he takes some quite good ones to illustrate his articles. Those are what make the difference.
An article might also express an opinion and present the facts/evidence as you see it. They might also be a way of passing on tips on different fishing methods and if they're really good, because nothing on a website is removed, people will be referencing for years to come.
So why write a 'blog' when you can tell a whole lot more people about yourself, your methods and what you do by writing an article. If in the most extreme case we don't publish it (very rare cases), then you can always put it up as a blog. But an article will allow you to shine. Give it a go.
