There are quite some handy webtools for us users of the steem blockchain and today I present some of them and why you would go there.

Where I put @accountname this can be your accountname or any other persons accountname. I am not saying I am complete but these are the ones I use frequently. Another site called steemconnect is part of steemit and is used to connect your account to others applications.
My best 5:
- steembottracker.com
- steemnow.com/@accountname
- steemd.com/@accountname
- steemworld.org/@accountname
- steemauto.com
steembottracker
This extensive site you check when you plan to buy an upvote of one of many bidbots. You can see what bots are giving what upvote when and -more important - how many other persons have already placed a bid for that bidbot. The site advices a maximum bid to not get a negative overall return. Return is your part of the bid minus some 25% curation for others. Be aware that there are no guarantees. If others bid without looking they can ruin the return for al bidders.
The site also list a number of other bots like the large TIPU vote buy service or so called resteemservices. Be aware that there can be other bidbots not listed here.
Under the site header tools I often look at my delegations. You can first see them and easily change them here. In the past the 'frontrunning ' worked as well showing what posts were expected to get a high (paid ) upvote. Here you powudl normally see the posts we all see in trending each day! People woild vote on these as well to get some of the curation.

In steemnow you see on one page the latest upvotes you got and a total per post on het back of the page. Also your votingpower in % is given clearly. Each full vote lowers your voting power with 2% so after 10 votes it is 80% and requires a day to recover. ( PS: If you are above 500 SP you can give half votes or quarter votes etc and this will appear automatically ans is called a vote slider.)
steemd.com
I do not go here often but it comes in handy when you wanna see details at blockchain level. You see every transaction of an account going back forever I believe. Suppose you get a downvote you can check here if that person gives downvotes to everyone or only to you. Or you can see when you got a last upvote from someone etc etc. Also there are some details about the account itself included.
steemworld.org
First the maker asks for a future upvote on his last post but then you enter a site that is really state of the art I would say. It has everything you can think of. Delegations in and - out for instance so you can see what a whale is delegating to whom etc. Even better is that the tool can calculate your future (curation) earnings. If you live of curation (do we have such people ?) this shows if you can pay next weeks rent !!!!
steemauto
This site is for those who are a bit lazy like me. You can set up or follow a curation trail. I still find this difficult to understand exactly but by following a trail you give an upvote (large or small ... you decide in settings) to whomever this trail gives a vote. That can be a trail for optimizing curation or a trail for a certain nice group of people a bit like charity.
Assume you have a group of twenty with the same hobby the autovote tool allows you to give votes to eachothers posts without sitting behind the computer 24/7.
Do you feel a bit nerdy already ?

These were my top 5. Which site did I miss ?
