I have had problems with both tBlog and Technorati and I have written extensively about both. 

Technorati problems 

In June last year, I wrote about problems with Technorati tags, which we fixed by switching to Wordpress.  In August I wrote about how tBlog and Technorati were not compatible.  In July, we even dumped tBlog to take advantage of tags.

tBlog problems

In February, I wrote about the challenges of monetizing your tblog blog.  And for a while, these guys were putting popup ads, which are such a no-no these days.

The good news

About six months ago, while Technorati tags wouldn't work, but our posts were still indexed by Technorati and people there could find my blog in a search.   Then one fine day, no matter how many times you pinged Technorati, nothing would happen.

Guess what, today, you can see that Technorati is once again indexing tBlogs.  I have no clue if it was Technorati or tBlog that fixed the problem, but it means I might stick around here a little longer.  Take a look at my listings.
