Beta Blogger team has rolled some of the new blogger feature into the old blogger, for example, the link to create a new blog is now redirected to the new Beta Blogger rather the old blogger. This way, no more people will be using the old blogger and minimizing their efforts to make the transition process as easy as possible. But of course, you can still create a new account on the old Blogger if you want to join a team blog, or are using a language that haven’t been added to the new version of Blogger.
When i saw an article called "Why can't I switch to Blogger in beta?", i finally realized the answer for my blog problem. Here's the complete article:
While the new version of Blogger is still in beta, some users with certain types of blogs will not be able to switch to it. We'll be adding support for these blogs as soon as possible, so everyone can join in the fun. But for now, if you have any of the following on your account, you'll need to hold off for a bit:
* A very large blog. (More than a couple thousand posts + comments.)
Note that, even if your blog is eligible to switch, you may not have the link to do so on your dashboard. We are starting out by just switching over a limited number of accounts, but we'll add more and more as time goes on. However, if you still want to try out Blogger in beta, what you can do is to visit beta.blogger.com and create a new account. Later on, you'll be able to merge this account with your original Blogger account.
Thanks for your patience, and we promise it will be worth the wait!
I have 864 post currently (including this post and it will grow in daily basis), but i don't know how much comment are there in my blog (not too much i guess). Maybe that's why i still don't get the option to upgrade to Beta Blogger. Maybe i do have to wait a little longer to get into Beta Blogger :D
