Lazy intro (with Disclaimer)
These are perhaps the top two free blogging sites around. Having a Google account, I automatically got one at Blogger. So far I never bothered to use it, as I already have two with WordPress. But today I decided to kill time with it, and I did find some plus points over WordPress. (This is from the perspective of a WordPress user for 6 months, at the same time being a Google user for 5+ years. If you are looking for detailed reviews, there are plenty on the web. Note that I am referring to wordpress.com and not wordpress.org, since we are comparing with the “free” Blogger here.)
WordPress offers thrice free space (3 gigs) compared to Blogger (with a catch: Google shares the storage with its other services like Picasa etc.). Assuming half a gig dedicated to Blogger, it should be enough for people with more text to write than fill the blog with space-consuming pictures. A page-long text blog (with links) would hardly take some 100 kilobytes.
Photo-bloggers do appreciate that extra space, but in reality, even 1 gig of space can offer 1000 posts each taking up say 900 KB of a photo and 100 KB of text. One needn’t upload the original big size image file on a website – it is better to upload a smaller resolution to facilitate quick loading, both for the publisher and reader. Videos can be embedded in the blog, while actually using the storage space from video sharing services like Youtube. One can also embed a photo from another web album, thereby not duplicating storage of the same file.
The latest storage specs from Google, considering with/ without Google+ can be found here and here. It seems Google+ is offering unlimited storage for all images uploaded to it which are less than 2048×2048 pixels or 4 MP.
For Google account holders, Blogger would be attractive with the Single Sign On facility. The same session can be used for mail, chat, blog, web album, docs, etc. Also Blogger is faster than WordPress. But here is one fact: WordPress has a bigger community of bloggers, because this is what it was intended for. Whereas Blogger adds to the number of services Google offers to its account holders. This is why Google shares your blog storage space with its other services. But wordpress is just blogging; no combo offer!
Perhaps the greatest advantage of Blogger is that it has opened its CSS completely. If you are looking for more control of colors, background and stuff, then Blogger is your stop. In WordPress, one has to purchase CSS upgrade to customize layout, colors etc., if not satisfied with the limited number of themes. In Blogger, one can edit or replace the entire CSS without any paid upgrade. If you are inspired by the better themes of WordPress and know CSS, you can make one for Blogger yourself. And if you want to learn CSS, what better a playground than Blogger? Maybe the addiction will make you open a new blog and publish only CSS templates!
WordPress is better for space-intensive blogs with 3GB storage, but Blogger has more ability to customize. For bloggers between these extremes, the differences don’t matter; the content of the blog does.
