Basic overview of the most popular reliable free blog platform services.
Blogs that comes with an album attached directly to it.
Popular Blogs: WordPress, Blogger (use Picasa and Google Docs), Tumblr (no frills mircro blog, get 3rd party services to build your blog)
Blogs with direct attached albums: Multiply (no limit even on free), LiveJournal (very limited), WordPress (generous 3GB for files and photos) (each allows upgrades for a small annual fee.)
Blogs that have files: WordPress (limited extentions), Multiply (limit to 3 attachments per post). Use Google Docs with Blogger. Third party files can be linked to your blog including MSN SkyDrive.
Blogger, Multiply, Tumblr allow customizing with CSS code access, also plenty of free templates to choose from.
Wordpress allows customizing to a point (add banner or background on selected templates) or pay an annual fee for CSS access to customize. Each WP template comes with a pre-established font.
LiveJournal is very limiting to customizing unless you pay.
Java-scripting: Not allowed on WordPress or Multiply. AdSense or some counters have java-scripting codes.
Stats: WordPress has the best free stats. The others have something, except Tumblr (has none), but you can add third party stat applications.
Posting: If you can write emails, you can post a blog as most of the editors are the same.
Some blog platforms allow you to post by email or mobile device if you want to get fancy.
Most allow you to use the free download of MSN LiveWriter also.
Pages: WordPress = unlimited. Blogger/Blogspot = only 10. Tumblr = depends on the template you select. Multiply = Reviews pages with a date. LiveJournal = none.
Comments: Do you want interaction and people to post comments on your blog or if you are just giving out information of a specific topic and comments don’t matter?
Some blog sites require that members only of that blog site (like Multiply) can post comments, while others allow you to open up comments to anyone.
This also means you might get lots of spam (unwanted) comments also if you leave it opened to the public.
Blogger/Blogspot and WordPress both have comment/spam controls. At WordPress, you can edit a posters comments unlike other blog sites.
Ads: Most blogs are free supported by ads, with the exception of Blogger (no ads) however, if you need more space or want to get rid of the ads, then you will have to pay an annual subscription to remove them.
Blogger does not have ads unless you use your AdSense account.
Since AdSense is a java-script, you cannot use it on blogs that do not allow java-scripting (see above list).
To make money from blogging, you have to have an established topic with gained established readers. The more topics (with good titles for searches) and readers you have, the more traffic you get, then you can make money if they are clicking off the ads while on your site, leaving your site, and having adventures elsewhere on the net.
If a reader is using RSS feeds in a blog reader, they will not see the ads, only your posted articles.
In some RSS Readers, they may share your article with friends, they can even repost your article by emailing it to their blog.
Some blogs also have “email” feature but it could be either the whole article or the link to the article, so check out the service to see what a person will get.
IMPORTANT: You must have x amount of money earned in your AdSense account before you get paid.
Whatever you post to the net, is there forever even if you delete your blog (some you cannot delete yourself), someone can still find it, there are ways.
So be very careful of what you post.
