Blogs were kinda lame. The majority of blog entries were "look at my bald guy in a diaper" or "i just made a new title screen". Very few people were using them to blog things of any importance so it's not like we lost something we needed.
All of those people moved to the base & title screen forum. Now instead of having their posts able to be hidden from the front of the members page, they're guaranteed a front spot on the forum page.
The reason blogs were used poorly is because BYOND actually has a small number of game developers and because there was no direction about how the blogs should be used. If these three things were made clear:
1. BYOND is a game development community.
2. BYOND blogs are for chronicling your experiences in developing BYOND games (if you want to tell people about what happened in school, get a tumblr or something else).
3. BYOND game development is not about ripping or drawing "bases".
The blogs would have been a valuable resource. You could read a blog to follow the progress of a game's development. If you find a library to be especially useful in your game, you could blog about it to let other people know about the resource and how to use it. If you run into a problem while developing your game, you can blog about it and get meaningful help - you don't have to summarize your problem in half a page on the forum, you have an entire blog of background information about the project.
The blogs were a place that actual discussion could take place and provided a way for people to get to know each other as game developers. With only having a forum it's difficult for people to become interested in each other's projects. BYOND's strength should be that it offers a community of game developers to help you refine your game ideas. While BYOND doesn't have many people who know anything about game development and could provide useful input, it doesn't have the mechanism for this type of interaction either.
Tumblr, blogspot, and wordpress are all free to use if you need a blog. Webs is an option too although they kinda suck. Here's my crappy website made with Webs from back in 09. Lol I can't believe I thought that was presentable.
