Steemitbc Logo Design Concept

Just wanted to put my design concept in a post to provide more background information and in case it gets lost in the comments of this post:
https://steemit.com/community/@steemitbc/looking-for-a-logo-20sbd

This was the design brief:

Here are our thoughts and what we are looking for:

• Logo could incorporate "blockchain" into it.
• Logo could include BC or Blogger Central
• Logo should be clean and able to fit into our profile thumbnail

Our motto is "building communities and empowering leaders". This phrase may also help aid you in your design.

I remember seeing some icons depicting the concept of block chain, which I used to create a custom font for the letters 'B' and 'C' and when combined with the initial sketches of the steemitbc team this is what I came up with:

Since I quite liked the concept, I decided to refine it further by creating a more polished version with more details.

First I started with the letters 'B' and 'C' and tried two different styles:

Then I incorporated the chat icon into the design because I thought the two speech bubbles worked quite well with the two letters:

Then I tried some colours and made sure the design fits nicely into a circle:

I thought that the blue theme looked nicer and wanted to accentuate the chain image of the blockchain more by making the interlocking rings, but I realized that I also need to make the font more legible (I used Clear San Medium):

As a final check, I wanted to make sure that the logo was still clear and distinguishable in a small size:

So there you have it, the logo contains two difference references to the blockchain in the customized font and interlocking speech bubbles; it uses the concept of chats and the letters B & C to reference blog central; it fits nicely into a circle and the colours is interchangeable depending on the theme you want to apply (steemit blue or other colour palettes).

I have enjoyed chatting to various people on Discord that are associated with #steemitbc, and very grateful for the opportunity to contribute to the logo design idea. I hope you can provide some suggestions and feedback to help me improve the design

Finally Hive account@paulag if you are on the look out for a logo or banner, I would be happy to come up with a design for the great people at #bisteemit as well :)

Update:
There were some variations that I thought would be good to test here and get some feedback on as well. I tried to use curves in the letters 'B' and 'C' instead of straight lines and I think it looks better:

And also a variation with a very light grey background and a circle around the logo, which I didn't think improved anything:

Oh, and one more thing, I have made the letters more visible in a small size, and left one or two of the 'blocks' in the blockchain unfilled:

Update:
Based on some feedback/suggestion, here are some other variations to consider from left to right (Original; more square speech bubbles; remove chain link appearance of speech bubbles)
