PayDelete

The DeadDelete Plugin for WordPress allows developers to make removing outdated content from their sites easy by allowing users to click a button that checks source URLs for 404 or 301 status codes. If the source returns a 404 the post is trashed. The same is true in cases of 301s if the final destination is known to be a destination for missing content.
DeadDelete is designed primarily for aggregators that copy content from other websites with source attribution links included. It is ideal for RSS based auto-blogs that include a large amount of content from other sources. With DeadDelete a user can click a button when they notice that an article is based on a source that no longer exists and remove your copy so that you don’t have to.

Replace your text widgets with Inserts that are made of a custom post type.
You can classify them, tag them, restore revisions, check the author, and find the modification history. They are easy to edit with the WordPress editor (well, as good as that gets) and you won’t be editing them in a tiny narrow column on your widgets screen.
Once you create your insert, you can use the Insert This! Widget to display it in the sidebars or choose to use a shortcode instead and display your insert any where.
Intelligent Content Inserts are theme independent. Inspired by Justin Tadlock’s QueryPosts widget and the Featured Posts/Pages widgets from StudioPress, this is an easy to use and theme independent way to manage text you want to have appear in sidebars. In addition, I have provided a shortcode so you can display these inserts in any page or post.
For improved administration of your sidebar content, the widget lets you set a widget title, so all your text type widgets won’t look alike, then you can choose not to display the title on your web page! You have three choices for title display: no title, widget title, or insert title.
The widget also allows you to set a css class for your insert.
Why use Insert This! Intelligent Content Inserts?
Here is a perfect use case: you have an address that you have to show in the header on the home page, on a sidebar inside, and in the text on a landing page. Your client moves! If you use an insert then you only have to change the address once.
Here is another: you have the board of directors displayed in a sidebar. Your client wants to edit the list. If you used a text widget then you have to explain all the html, and apologize for how difficult it is to edit. Maybe you provided the Black Mountain Tinymce editor for them, to improve the experience, but it is still not the best user experience from WordPress. Or perhaps you used Queryposts or something similar and you have to explain to them that the board of directors is on a page (or a post) but it doesn’t show up in the blog or the menu.
With Inserts your client can just go and look up the insert named Board of Directors and edit that, no confusion about a page or a post.
Here is another use case: you have several advertisers and several styles of advertisement. In your sidebar, they all are titled “Text” because you don’t want to display a title.
Instead, use Insert This! Intelligent Content Inserts and create your ad code snippets, with relevant titles. Then you can classify them as Ads, tag them etc in your Inserts edit panels for future management. Now just add the ads to your sidebars via the widget. Choose a helpful title on the widget, so you can differentiate your ads in your sidebar, and select “no title” for display!

Insert This! Content Inserts

Use Inserts to manage sidebar content instead of text widgets.  Identify inserts in widgets with titles; organize with taxonomies.
