I never quite got "into" WsW but LWA is one of my most used programs.
With WsW I can tell it could probably save me time one it's all set up like I would like it, but it costs time to figure out, and I simply never spent that time. I did try since i had LWA and i thought it'd be nice to have WsW to check and update pages snapped in LWA. But it turned out to be time consuming so I gave up. This was 2005 or even 2004 so it's probably smooth and wonderful now, and I'm more patient, so I will listen and try it again.
I have said before I trial lots of software and realise halfway through the trial that I don't use it... But with LWA things worked differently - i was surprised one day within 2-3 weeks of install to be told "you have have hit the 100 documents limit" (not a limitation of the free version anymore) - needless to say I registered it and have been moving it from PC to PC since. It's one of the first things I reinstall after the security and utilities, along with a browser (which has changed from mozilla to slimbrowser to kmeleon to opera over the years - all of which happily worked with lwa), email (poco, which happily worked with lwa, and now opera, which alas doesn't at the email level), and text editor.
LWA is worth a try because it gives you a place to save web documents but also other documents which is independent of the tools you use. I don't know about you guys but I have used 6 or more different browsers in the last 2 years (ie, ie based slim browser, kmeleon, netscape, mozilla, firefox,seamonkey,opera), and several email clients. All other tools I know of either work on cut-and-paste, or only work in one or two browsers. When you switch browsers, you either lose your archive or have to cut/paste it all over...
Things I have done with LWA:
* keep a snapshot copy of order confirmations on ecommerce websites
* keep a (temporary) snapshot copy of ebay item description pages for items bid on, in case the description is amended later, so I can complain if needed
* keep a snapshot copy of T&Cs from companies I do business with, so if they change I have the one I "signed" to on record. For example a deal offered by an energy supplier, or a subscription based website etc.
* keep a copy of maps and itineraries so I can take them with me offline if necessary (I had a 9" subnotebook)
* keep a snapshot of sofware description pages with a note with the executable name (so when a month later I'm "what was this download again?" I have a quick way to check) and opinion notes after i try it
* keep recipes
* save key emails outside the email program, just in case, or to store them together with a snapshot the website/pages they refer to.
* snapshot of website visuals and web projects at different stages. Again, mostly useful to remember or if the client tries to be silly.
* snapshot of product pages when doing research for projects - it's much better than just a bookmark. I have folders on ecological paints, multi room sound systems, hotels in X, or topics from work
* snapshot of technical tutorials and reference information - again those sites disappear from the web sometimes and bookmarks don't help much. There are some key perl sites which have disappeared and I wish I'd snapped more pages there.
It's not perfect, but it's much more useful than you'd imagine.
