Tip: Editing old post and using the HTML comment tags to hide the original

A blogger asked: "if a do a post/message in blogger. And after I rewrite this post. But more later I want to replace (substirute) the rewrited post by the first original post. How can I do it?"

I assume the above implies frequent editing of old post and the possibility of reverting to the earlier/previous edition after editing. Now the problem is the previous edition would most probably have been overwritten by Blogger.com's automatic saving, so how to revert to the earlier/older edition?

Here is what I would suggest. Suppose I now want to edit an old post. What I would do will be to first copy-paste the whole original post within the same post under editing with one following the other so that there will be 2 duplicate copies of the post with duplicate below the original.

Now I would surround duplicate with a pair of the comment tag <!-- and --> like this (anything that is surrounded by the pair of comment tags will not be displayed by any browser):

Enviroman says: "We must take very good care of our 1 and only Spaceship Earth without lifeboat. Where can we go if something terrible happen to our spaceship and it become unlivable? What will we leave behind for our children, grandchildren, great grandchildren? What kind of legacy are we leaving behind?
<--

What will we leave behind for our children, grandchildren, great grandchildren? What kind of legacy are we leaving behind?
-->

Perhaps for extra measures, we may append an Version note and date, like for example, Version 1.0 14 February 2010, so it become

Enviroman says: "We must take very good care of our 1 and only Spaceship Earth without lifeboat. Where can we go if something terrible happen to our spaceship and it become unlivable? What will we leave behind for our children, grandchildren, great grandchildren? What kind of legacy are we leaving behind?

Version 1.0 14 February 2010:

What will we leave behind for our children, grandchildren, great grandchildren? What kind of legacy are we leaving behind?
-->

And now we can confidently edit the first duplicate and if we don't like what we did, all we have to do is to discard it and remove the pair of comment tags to make the original display.

If you don't like the above method, perhaps you can copy-paste the original post to be edited into a new post, then save the original as draft. If you don't like the new edited post, then discard it, go back to the draft and republish it.

Blogging tip - search definition (general)

I plan this to be a series of tips and tricks for blogging in general, not only related to Blogger.com platform, but applicable for any blogging software including Wordpress, Live Journal, Jomlah, etc.

I will start off by one simple little search engine trick I often use. Frequently, I like to define some word before writing about something related to that word. What I will do is just to type the word "define" before the word in a search engine.

For example, I want to publish a post about diabetes. Searching for [define diabetes]. Further, you can use different search engines depending on what kind of results you want.

If you use Google.com, the very first result will usually be the Web definition:

Web definitions for diabetes
a polygenic disease characterized by abnormally high glucose levels in the blood; any of several metabolic disorders marked by excessive urination ...
wordnetweb.princeton.edu/perl/webwn - Definition in context

If you use other search engines, the first result will not be as consistent. For example, using bing.com, first result was from www.diabetes.org:

American Diabetes Association Home Page - Aerican Diabetes ...
The American Diabetes Association is leading the fight against the deadly consequences of diabetes and fighting for those affected by diabetes.
www.diabetes.org Cached page

but the first result for asthma was from

Asthma UK - Homepage
Asthma UK is the charity dedicated to improving the health and well-being of the 5.4 million people in the UK whose lives are affected by asthma.
