#26 - a little too simple for what we have in mind. But there's something classic about the blocky style you've chosen. Not sure how to recommend that you proceed. One idea is to try incorporating a cloud into the logo.
#61 - reminds us of a social media logo, which is both good and bad. Good because it evokes an idea of connected people and ideas. Bad because that's very consumerish and we're a more conservative, secure business software application.
