The correct Addthis url for your blog got de-linked:

Try this instead:

http://www.addthis.com/bookmark.php?&url=http://lotgk.wordpress.com/2008/09/25/check-out-the-giant-beaver/&title=Check%20Out%20The%20Giant%20Beaver

The Addthis button you have in that post goes to this url:
http://www.addthis.com/bookmark.php?&url=check-out-the-giant-beavercheck-out-the-giant-beaver%2F&title=Check%20Out%20The%20Giant%20Beaver

Look at the part after
http://www.addthis.com/bookmark.php?&url=
It has no http:// ....

This should not have been so if you were using the one-click bookmarklet.
The one-click bookmarklet would have created a link that looks like this:
http://www.addthis.com/bookmark.php?&url=http://lotgk.wordpress.com/2008/09/25/check-out-the-giant-beaver/&title=Check Out The Giant Beaver

Click the link above and try to mail yourself your article. You should have the full url.
I y-mailed myself your post using the above link and I got the full url:
See a screenshot:

If you produced the link using the bookmarklet, I wonder why it didn't work for you. It works flawlessly in Google Chrome and Firefox. Are you using a diffferent browser?

One of my posts has the Addthis button launched via the bookmarklet:
http://shongjog.wordpress.com/2010/07/07/how-to-add-addthis-in-a-wordpress-com-blog-post-in-one-click/

And the Addthis button goes to this url:
http://www.addthis.com/bookmark.php?&url=http%3A%2F%2Fshongjog.wordpress.com%2F2010%2F07%2F07%2Fhow-to-add-addthis-in-a-wordpress-com-blog-post-in-one-click%2F&title=How%20to%20add%20Addthis%20in%20a%20wordpress.com%20blog%20post%20in%20ONE%20click%20

Note that the blog post url is complete and not truncated.
When I try to y-mail it, I am able to do so.

Your code leaves out critical parts of the link.

Addtoany is my favourite too, primarily because I learned to code my bookmarklets by dessecting their code for wordpress.com share button :p

The Addthis button I coded is coded after the Addtoany button and works like it ((just a click to add the button to your ready to publish post)).

Advantage of Addthis:
The publisher has analytics if (s)he is an Addthis member.

Advantage of Addtoany:
It has a cool "email a friend" option that lets the sharer pull email addresses from their address book.

It is not mandatory for the title to be a link in the Addthis page. But it is mandatory for it to be there to work properly when someone wants to share a post in a sharing site.

Although the title does show up, the link is inactive, and it does not work.

I clicked the link, selected Yahoo mail to send, and when i received my email, the title was there, however, the link was not active.

Best of luck with your hunt! :)

Thank you everyone for your help. I'm glad that wordpress has such a big fanbase and very helpful people willing to give their time to help one another. Anyway, I will try to experiment with the other options that timethief presented (thanks!).

However, it still seems lacking that WordPress features all these awesome features but still has not yet developed a basic easy social sharing tool for blogs. I'm not sure why it hasn't, but it would most certainly be a very useful tool for millions of wordpress blogs.

Yeah, so anyway, thanks for all your help!

Yes, addtoany works perfectly. Because it is perfectly coded.

But not the Addthis that you have been using. Did you try to click Addthis button in one of your blog posts without clicking the blog post title first? Say, when I go to your homepage and click the button in your latest post - which for the time being is "Lost Chronicles – The Lost Episodes" - then the button takes me to an Addthis page that doesn't contain the blog post title or blog post url at all. I can share only the blog url and that too without the blog post title.
See a screenshot:

Even if I click the button after clicking a post title first, I am not able to share the blog post with the post title, only the blog post url is present.
See a screenshot:

The one-click Addthis button is coded just like the Addtoany button - so, it does its job of sharing a blog post url and a blog post title perfectly.

Click to the bottom and click the social link.

Also the code you are using is faulty. Read this post to know why:
WordPress pranks – prank no. 4

It is possible to have an Addthis button that really works and that too without even leaving the blog editor after you publish a post:
How to add Addthis in a wordpress.com blog post in ONE click

Then save that post, DO NOT PUBLISH IT.

Now, whenever you want to add a new post, go to your drafts page, select that page, copy all the code on it, and then create a new post.

It's how I do for my blog, and each category has different pictures, links, and set up design. It's the closest thing you can get to your blog being a webpage, web site.

I just am not thrilled with the very limited designs
If how your icons look for is important to you and if you have seen a particular set of icons that you want for your blog post, then mention it in this thread. If it's possible to have it in wordpress.com, I can create the codes for you so that you can have your own design and own set of icons.

The socialbookmarks we can use on wordpress.com blogs are found here > http://onecoolsitebloggingtips.com/2010/04/08/social-bookmarks-for-wordpress-com-blogs/ That post incudes: archfx, perlitalabs, getsociallive, AddToAny, Digg Buttons, Tweetmeme Buttons, (__Add to Stumbleupon, __Add to Del.icio.us, __Add to Digg.com, __Add to Reddit), Publicize, Facebook Badge, Twitter Widgets, AddThis Widget.

Also, it is not possible to do it automatically in wordpress.com - whatever solution you use, it is a do-it-in-every-post method.

I really want a social sharing thingy like others are using through the getsocialalive tool, but I just am not thrilled with the very limited designs and the fact you need to post it to every single post. Seems like a hassle...

Does anybody know of any better alternatives for wordpress.com? Thank you!
