creator here!

tl;dr: yes, it is a little aspirational as of now, but will change.

The first search you can do, since I equate "star count" to popularity, and by default all results are sorted by star count/popularity.

The second search will be entirely implemented soon. You can find repos similar to other repos according to their tags, but can't sort by created or updated date yet. The information is there in the data, I just need to finish that functionality in the search and sorting.

I wanted to try to get something out the door before I finished every feature to see what people would use and what requests/issues people would have, and prioritize accordingly. Otherwise I know I would spend weeks fleshing out every feature I thought I wanted, including many that most would find useless =(.

In retrospect, you are correct in that it is a little misleading since you assume you can do that yet. It will hopefully be corrected shortly (busy trying to keep things running smoothly!).

Thanks for the input troutwine! I'll finish this functionality hopefully this week (if not sooner).

I hope to see something like alternativeto.net too, were you can link multiple items and compare facts about them. I realize this is what can be done with the tags. It can be easier to see which programs are similar than coming up with a unique tag for them though.

Thanks and good luck! Do you have a twitter account I can follow for updates to gitrep?
