Our target audience are software developers on Windows platforms developing complex multi-threaded code in unmanaged languages; so, in general, they're quite hardcore techies.
Things that the logo could/should communicate include:
+ finding things (in our case deadlocks and other locking issues in code) perhaps a magnifying glass?
+ exploring and delving into complexity to look at small details
+ locks, but not keys
+ threading? different paths using different locks?
The website http://www.lockexplorer.com has more details should you feel you need it...
It's VERY important to us that the new logo should work well with our other websites (see http://www.serverframework.com, http://www.jetbyte.com and http://www.lenholgate.com) - however, feel free to surprise us (as long as the logo works with the other new sites and suggests a common branding we're happy).
Particularly, we currently feel that the new logo should use the black, red and white colours that are used on the other sites and should be suitable for use on a black banner in a similar way to the http://www.serverframework.com logo is.
We'd like a favicon that uses an element of the web logo.
We'd like to see how the logo could also work in print, headed paper and business cards may be required and so although the initial web logo needs to work on a black background, variations should work on a white background too.
Right now we have it in our heads that the text should likely be in the same font as the other sites, this is "Walkway", but we're not wedded to this too much as long as the logo works and the common branding can be seen.
Although we have a rough idea of what we want we'd like to be surprised and are happy to keep an open mind.
