Why not change the name "tweetlater" to "tweetstream" or something that's not going to raise suspicion? I agree with a previous commenter: I use your service when I know already what I'll pretty much be doing at a specific time and know that I won't be able to pick up my cellphone and key in and send 140 characters. Like today. I have a plan and I have outlined it and timed it out on tweetlater. Not only do my people know what I'm doing, but I made myself a mental guideline by setting my day up on tweetlater.
