Write, preview, publish, and archive your blog from a Mac.
Browser-based interfaces are slow, clumsy, and require you to be online just to use them. Browsers are perfect for reading web content, but not ideal for creating it. If you're serious about writing for the web, you need a desktop blog editor. If you're lucky enough to have a Mac, nothing is more powerful, or more elegant than MarsEdit.

Have you ever wanted to change the extension of hundreds of files at once? Or have you ever needed to change an email address on 50 different pages of a website? Then MassReplaceIt is the tool for you.
MassReplaceIt takes a list of files, searches either their contents or their filenames, and replaces every occurrence of your search term with something else. Not only that, but it provides numerous features and options to give you control over the changes you want to make.
For example, you can optionally create a mask to filter which files are searched. Say you have a folder with thousands of documents inside it, but you only want to search html files modified in the last week. MassReplaceIt makes it easy to do this.
