Simple, yes. Useful? Minimally. By comparison to FrontPage 98 it's a toy. (FrontPage after 1998 went into a downwards death spiral comparable to the post 1997 collapse of Microsoft Word.)
So then I tried NVU, an open source Java app. It's a partial clone of FrontPage 2000 (shame they didn't clone FP 98!!). It's far beyond RapidWeaver, but one of the first things I did was create an anchor on a page, then create a link on the same page to that anchor. The HTML was well formed, but the GUI didn't create a viewable link. Ooookaaay, so much for NVU.
Well, there's always the ghost of Mozilla composer, though it's very much a page rather than site oriented application. Then there's Dreamweaver, with its increasingly feeble OS X support. I suppose there a bunch of other page oriented solutions.
Here's Faughnan's test for a serious web authoring tool. I don't think any OS X app can pass this test today -- FrontPage 98 did it well:
- View a web site as a file hierarchy or a directed graph of links.
- Click on page icon see metadata, drag and drop into a page to create a link with text taken from target page title.
- Create an anchor on a page. Drag and drop to create a link to anchor. Drag anchor to another page to create a link.
- Change the physical location or file name of a page. Have all links in web site update to reflect this change.
- Blogger with TextArea support for Firefox/IE (but not Safari)
- Slightly more sophisticated blogger solutions
- Various page oriented solutions (wordprocessor save as HTML)
- Toy site management tools like RapidWeaver
- The missing domain once inhabited by FrontPage
- The missing domain once inhabited by Dreamweaver
- Industrial content management solutions that aren't particularly author-friendly and cost thousands of dollars.
