The site design is decent but design comments is the only feedback you are going to get as that is all anyone can determine from your site. Some examples would be nice. How about the difference between standard personalised hashtagging and highly personalised hashtagging? A sentence or two about your technology stack?

If this is simply a test balloon to gather reaction for some potential software then great, it's an interesting notion but not one that warrants my email address.

Also, you may want to think about adding a middle tier option for occasional tweeters at a reduced price. There are a lot of people that send more than 5 tweets per day (but not much more) and will perhaps feel 5 euro per month is too pricey.

Thank you for your advice! I will add some examples and explanation in the near future. To add a middle tier is a good idea, thanks for the tips!
