EPTAligulac.com is an ongoing statistical project and website in development started in December 2012. It offers a comprehensive database of games from the pro and semipro SC2 scenes, as well as a unique rating system aimed at rating players and teams, and predicting games.
The FAQ might be able to answer your questions. If not, I'll be keeping an eye on this thread so you can ask away here. This thread is also for suggestions and feedback.

Stories: yellow dots on players' rating charts to show important career events. Also red dots for team switches.
Added comparison feature to help compare players directly against each other.
Improved error/success/warning/info messages for every page.
Player match history filtering significantly improved.
Condensed the small events lists.
Predictions are now default best of 1.
When searching for events, you can now use quotes to improve results (code S used to match code A because the S matches the S in GSL, now you can write "code s" to get what you want).
URL shortener function for every page. (Button on the bottom.)
Rating algorithm updated. Koreans now start with 1200 points, offline games are weighted a factor 1.5 and we got rid of the need for fake games to avoid infinite performances.

Prediction format for proleague-style matches now available.
Performance optimisations to the balance report page and players' earnings pages allow these to load much faster.

Single elimination brackets now support BYEs. This can be used to simulate more exotic types of brackets.
The rating charts now indicate the time of the major balance patches. They are: supply depot before barracks (1.1.2), removal of Khaydarin Amulet (1.3.0), Infestor nerf (1.4.0), Queen range buff (1.4.3) and of course the HotS release.
Matchup statistics now shown for every rating list.
We now have a rank of player earnings. Prize pools are tied to events, so you can see the history of a player, as well. Most of the major prizes should be entered, but the weekly cups are still missing.

Changed rating system to allow players who play rarely to adjust quicker, and player who play more often to adjust slower. Overall uncertainties increased to compensate for the overall decreased speed of adjustments.
Match listings now have icons indicating whether a match was played on- or offline, and whether it was WoL or HotS.
More information on player, team and event pages. Events now have matchup statistics, homepages and Liquipedia links. Players have earnings and a ratio of offline matches to their total. One interseting thing is the MC number, inspired by the Erdos and Bacon numbers. To get an MC number of one, you have to play an offline match against MC. To get an MC number of two you have to play an offline match against someone with an MC number of one, and so on. MC was chosen because he is the player with the most offline games.
There is a new balance reports page. This will be expanded as we think of more statistics to produce.
Player match histories are now also filterable by game version and type (offline/online). Lifetime head-to-head records are best checked using the results search tool.
Ditched the server-rendered charts for an interactive javascript library.

Player match histories are now filterable by race, nationality and series length.
URLs are now generally human readable, e.g. http://aligulac.com/players/10-Stephano/ instead of http://aligulac.com/players/10/ (the latter will of course still work).
Ratings are now updated every six hours instead of every two weeks. The periods are still two weeks long, you are just seeing a preview of the next rating list that is kept updated.
The "most specialised" statistics on the rating lists are now weighted towards the top, to provide more relevant results.
The rating system now uses the logistic distribution instead of the normal. This helps accuracy in cases where the skill disparity is large.
General backend optimizations.

Fixed a serious bug in the model fitting code. The predictive power should be greatly improved.
Everyone can now add games. Publically submitted games are subject to review by the staff. (Staff positions are still open for those interested.)

Matches are now browsable by events.
Match search function now available. Search by player and event.
Rating adjustment pages now show more information about the rating calculation.
Player search has been heavily improved and applies to the top-right search box, as well as the search functions for predictions and match search. These functions will now search by player tags, team names, player and team aliases, country codes with two or three letters, as well as the commong English names for countries (in cases where these are one word), races (P, T, Z, R=Random and S=Switcher). It's still possible to use player ID lookup if necessary.
Rating lists are filterable by race and nationality.
Menus reorganized.
Created a database statistics page, where you can also download a SQL dump of the whole database (sans ratings and sensitive information).
Rating deviations are now displayed on the player pages.
Improved the player rating chart, showing changes in rating deviation over time.
