In everything, there can always be pros and cons even for giveaway. Like you, I have run giveaway in the past like many others. Giveaway is a good way to excite the community and give the new member little candies as well to raise their motivation in steemit. There can be many followers but how many everyone is having the idea of mutual support as a community. Many can just be takers and not return anything to the steemit community. A bit of random thoughts of mine. You are definitely a great lady with a great heart to help the steemit community.
