[Radiant] How do you manage blog items?

[Yusuke SAKATA]

Hi,
I just have started to use Radiant.
I really like Radiant.

One thing I am wondering is when I use it as a blog software.
I tried to put 20 articles under articles folder.
It is Okay.

When I get so many articles, like 300,  in the future, how can I
manage those items?
Is there any system or plugins to handle so many items(childs) for a
parent item.
