Many users on Hubski spend time on reddit still. Hubski scratches a different itch for most of us though. Like Herunar mentioned, it's smaller and less fast paced. I would say that "quaint" is probably a good description. The truth of the matter is, most of you that are here today, will not be here in 5 days, let alone 20. I think it takes about 20 days to really get hubski. By that time, you'll have much of the functionality down, you'll know some of the more prominent community members, you'll have the tags you like followed and you'll be actively participating in discussions beyond "why I left reddit." But most people don't make it to 20. Hubski expects more from it's community than other sites. Hubski is not fast-food.
Welcome! I hope both of you (and anyone else reading this) make it to 20.
