Let's be honest while we all love Steemit money is a motivating factor for everyone. I personally see nothing wrong with upvoting your own stuff, especially content moreso than comments but I see nothing wrong with that as long as people aren't using all 10 votes per day on themselves and are spreading some love around to the community.
If someone puts either money or time and effort into Steemit I see nothing wrong with rewarding themselves a bit. I tend to be more generous IMHO than most people on here and I feel I give a lot more than I get so for me I've been consiering upvoting myself more.
Glad to see some positive feedback on that.... The actual concept of that is very smart... Once we start having real big investors and corporations coming in and investing millions of dollars to buy SP either for marketing purposes or to pay their employees or service providers then we can say there is a real value that can make a difference... If the community or the company does not wish to go that way then they can simply remove the self-upvote button. However, I do not see that happening. If Steemit succeeds then we will be all surpised of the unrealized potential it holds. Have a good one! Tomas
