One thing is for sure, it is a good learning experience trying to write a bot, it also gives you a deeper understanding on how things work around here. I've been working on a curation bot for some time now, a bot that tries to find good posts by new and unestablished yet authors on Steemit and support them. It is already doing pretty well, though I'm doing changes and improvements all the time and I do check all of the voted posts manually do be able to further tweak things... guess how I found your post and which of the voters is the bot.

So by all means do try to write your own curation bot if you have some good ideas, people generally have negative impressions of bots, but they can also be used to help...
