I've been using Furl
online bookmarks. Furl allows you to maintain your own copy of a webpage
online and to categorize and tag webpages you save through Furl.
Unfortunately, Furl is disappearing. I've been wondering how long Furl would
last, since it didn't show me ads when I visited my Furl archive nor when
I bookmarked sites, so I didn't know how Furl was funding its continued
Furl is offering one the capability to transfer one's Furl bookmarks
to Diigo, so I signed up for a Diigo account
and requested the transfer of my bookmarks. I've also downloaded my
archived webpages from Furl.
If you want to check your HTML code to ensure that it is correct,
you can use The W3C Markup
. The service is free and will point out lines
in your code with errors. Even though a page may look correct when you
view it in your browser, it may still contain errors; the particular
browser you are using may compensate for the incorrect code or just
happen to present it in the way you expect, but other browsers may not
be so forgiving, so not everyone who visits your site may see the page
as you see it, if it has errors in the HTML code. Of course, due to
to variations in the way browsers interpret the code, the page may not
look exactly the same to all visitors even if the code is valid, but
you are, hopefully, reducing the chance of problems by correcting the code.
