No worries, the Steemd sites are just all of your Steemit info, steem power, reputation, voting power. Shows you who you vote for , who votes for you and what percent etc. It's just a general log of everything you do on Steemit, anyone can see it and if you want to find anyone elses you just replace the username in the url https://steemd.com/@xr-hammergaming i.e instead of xr-hammergaming, you would write the username you want to check out. I like to use it to keep check on my voting power as I like to keep it quite high so my votes are higher, eventhough they are still low lol. Also to see how long until my reputation changes since it shows you on a point scale, i.e mines 56.4, yours is 45.9 so you will get to 46 reputation soon :)

Happy to help mate!
