A minor point of irritation, for me, was to discover just how badly blogger.com treats things like meta tags.
Now I know full well that meta tags are not exactly ground breaking for SEO but when it comes to social linking several tags can be quite important. Specifically the meta description tag. When posting a link in facebook the meta description is the first source of content for describing the link.

I first noticed this when working on my Face Link tool which was created to make facebook link links for blogs. Here is an example of a good looking link to my blog. You can see that the tool was able to get a title and a description

Beyond making my little applications work the meta part of a web page also impacts of the quality of your search engine results listing. The description being used most often as the text that goes with the search result.
As such in a competitive market not using a description tag is a fatal mistake that your competitors will take advantage of.
So the result is not just that pretty much all blogger blogs produce rubbish looking links in facebook but that they have a significant disadvantage when the going gets tough. After searching for a while I have concluded that there is not really a decent solution to this aside from putting Google off with duplicate description and keywords.
In short blogger.com is not, in my opinion, suited to the world of web 2.0 nor business marketing.
